    <p>We have been developing a three-dimensionally (3D) structured complementary metal-oxide semiconductor (CMOS) image sensor (CIS), which has individual signal processing circuits in each pixel under the photoelectronic conversion area for high-performance and multi-functional operation. In this paper, we report on our experimental 3D integrated circuits developed using multi-stack technology, which enables us to fabricate 3D-CISs with small pixels. The results showed the fundamental operation of the prototype circuit, which indicates the feasibility of highly integrated 3D-CIS of More-than-Moore type applications.</p>

    A MEMS mirror that we are developing for a three-dimensional MEMS optical switch module features a terraced electrode structure that enables low driving voltage. The mirror can tilt more than 4 degrees at less than 80-V driving voltage. A control method for the MEMS mirror achieves a short switching time. We demonstrate 3 msec switching time.

    In recent years, room-temperature or low-temperature bonding technologies have attracted considerable attention and have become increasingly important for realizing high-performance multifunctional semiconductor devices featuring small sizes, low power consumption, high thermal dissipation, and high output power, among other properties. Sensors and microelectromechanical systems (MEMS) are typically made of Si and various non-Si materials, including glass, polymers, and piezoelectric materials, and require wafer-level hermetic packaging with small cavity volumes. Therefore, room-temperature or low-temperature bonding technologies with advanced features, such as low thermal damage and low residual stress due to the mismatch of the thermal expansion coefficients of dissimilar materials, are rapidly becoming popular for the fabrication of sensors and MEMS. This study focuses on surface activated bonding (SAB) using Au thin films for room-temperature bonding and introduces some recent research topics on hermetic and vacuum sealing of sensors and MEMS. It is expected that such technology can be used to fabricate gas cells for miniaturized atomic clocks.

    Recently high-level hermetic sealing is required for packaging of various micro-devices. In this report, we evaluated the applicability of thin Au/Ti films deposited on bonding surface and cavity wall to bonding and gettering material. We conclude that the thin Au/Ti films can be applicable to not only bonding but also gettering the gas atoms inside of a sealed cavity.

    To manufacture micro electro mechanical system (MEMS) device with a long term life and high accuracy, it is important to package them in a high vacuum. We fabricated a packaging structure after degassing annealing at 200℃ using Ti/Pt/Au films deposited on Si substrates. Then, by annealing at 450℃, thermally diffused Ti atoms reached the residual gas at the surface. It is assumed that a high vacuum packaging without encapsulating gettering material can be achieved by the proposed method, enabling simplification of the MEMS structure and manufacturing process.

    In recent years, high vacuum environment is required in micro-devices such as micro-PMT and bolometer. We developed a small vacuum pump for micro-devices that operate in ultra-high vacuum environment. The small vacuum pump was realized by anodic bonding of chip-scale glass and Si, which is the same principle as the ion pump. As a result, glow discharge was visually confirmed, and discharge characteristics according to Paschen’s law were obtained at a pressure of 1 to 1000 Pa.

    SnのX線吸収体とAlの超伝導トンネル接合[Al/AlOx(~1 nm)/Al]を組み合わせることで、広いX線エネルギーに渡りEDSの感度・WDSの分解能を両立するX線検出器が実現でき、SEM中で元素・化学状態の同定が期待できる。このAl超伝導トンネル接合は100℃程度の熱でも特例が劣化するため、十分な厚さのSn箔と常温付近にて複合化する必要があるが、Al・Snとも平滑試料の作製および酸化膜除去が困難なため、常温付近にて複合化した報告は少ない。今回、Al層に対してAu薄膜の酸化防止膜を付け、またSn箔をCMPにより平滑化することで、表面活性化接合を用いて常温での複合化に成功した。

    レーザドップラ速度計(LDV)はレーザによる非接触計測によって、鋼板や段ボール等、搬送の際の滑りや接触による損傷が懸念されるような場合でも正確な測長ができる。しかし、従来のLDVは大型であるため設置場所が限られていた。本研究では、それぞれがパッケージされ部品として完成していたレンズやレーザ素子等を、MEMS技術を用いて一体化することでLDVを大幅に小型化した。開発したLDVを用いた測長を行ったので結果を報告する。

    We report the first demonstration of three-dimensional (3D) integrated CMOS image sensors with pixel-parallel A/D converters (ADCs), thereby meeting the demand for high resolution and high frame rate imaging. Photodiode (PD) and inverter layers were directly bonded with the damascened Au electrodes to provide each pixel with in-pixel A/D conversion. We designed ADC with a pulse frequency output and fabricated a prototype sensor with 64 pixels. The developed sensor successfully captured video images and confirmed excellent linearity with a wide dynamic range of more than 80 dB, which showed feasibility of pixel-level 3D integration for high-performance CMOS image sensors.

    A robot hand is needed for many fields, which is capable of gripping various objects without slipping as human do. Slip detection sensor is necessary for controlling robot hand without slipping, and it need to be very small to be attached to robot fingers. In this paper, We have developed an extremely-compact laser Doppler velocimeter (Micro Slip Velocimeter: MSV) as a slip detector which is capable of measuring slip velocity. We have measured object velocity at 10 μm/s to 20000 μm/s with 3types of object material: Aluminium, plastic and cardboard. The output of this sensor is independent of the measuring material. MSV has great advantages for controlling robot hand to grip objects without slipping in various material.

    半導体レーザ素子のAu薄膜電極と平滑な表面を有するAuスタッドバンプをN2大気圧プラズマによって表面活性化することにより、大気圧雰囲気中での低温接合を実現した。発光分析からNO及びN2(2nd P.S.)の発光を伴う高エネル ギーの中性励起種が表面活性化に寄与していることが示唆された。N2プラズマを3分間照射したのち、接合荷重680 gf (320 MPa)で接合(接合温度:150 ℃)することにより、 MIL-STD-883G基準値を満足する十分な接合強度が得られた。

    The electrical properties of Si/Si, Si/GaN and Si/GaAs junctions fabricated by using surface-activated bonding (SAB) were investigated. Current-voltage (I-V) characteristics of n-Si/n-Si and n-Si/n-GaN junctions indicated ohmic features at room temperature. The I-V characteristics of respective n-Si/n-Si dice were close to one another. No mechanical deficits were observed in n-Si/n-GaN junctions after measurements in varied temperatures. The p-Si/n-GaAs junctions revealed good rectifying properties. Their flat-band voltage was around 1.6V, which is close to the diffusion potential calculated for p-Si/n-GaAs heterojunctions with no electric charges placed at the interface. These results indicate that the SAB is potentially applicable for fabricating novel devices.

    本研究室では、これまで最低限のコンポーネント、シンプルな構造とMEMS技術により超小型高精度の血流量センサを開発した。高感度な血流量データによりこれまで心電計や脈波計で検出していた脈波データが同時に得られるため、多変量解析の点で有用である。今回、体へのストレスの指標の1つである自律神経系より影響を受ける心拍間隔の揺らぎの変化を分析するプログラムを作成し血流量センサによるストレス評価について検討した。

    We have made a probe volume of a blood flow sensor about two hundredth of a conventional sensor by a fusion of SiP (System-in Package) and optical MEMS (microelectromechanical systems) chip. An improvement of fabrication efficiency can be realized, because structures of both SiP and optical MEMS chip enable wafer-level packaging. This newly developed blood flow sensor (SiP-MEMS blood flow sensor) is portable and can measure during moving by the wireless transfer.

    It is very useful to measure hemorheology to keep tabs on health. However, both place and time are limited for hemorheology measurement, since it needs a blood sample. It also can&prime;t measure noninvasively. So we try a new viscometry of static particulate solution by detecting particulate behavior due to the Brownian motion with MEMS blood flowmeter which is wearable sensor for monitoring blood flow noninvasively at all time as a previous work of noninvasive hemorheology measurement with MEMS blood flowmeter.

    The hybrid integration of multiple chips in three dimensions permits highly functional and compact optoelectronic microsystems. However, the chips tend to be thermally damaged during the several repeated high-temperature bonding steps in a conventional method using AuSn solder. In this study, three-dimensional integration of optical chips was successfully performed using Au-Au surface-activated bonding (bonding temperature: 150 -C). The size of the fully integrated microsystem is only 2.6 mm ~ 2.6 mm ~ 1 mm thick. The fabricated microsystem consists of two elements: i) a micromachined silicon optical bench incorporating a bonded laser diode, micromirrors, and through-hole electrodes; and ii) a glass substrate incorporating bonded photodiodes, electrical interconnections, and refractive microlenses. The silicon optical bench and the glass substrate were vertically stacked by surface-activated bonding. The design and fabrication process allow chip-scale and wafer-level packaging. In addition, it was applied to laser Doppler velocimeter sensor. The measured Doppler beat signal frequency was found to be very close to the theoretical prediction.

    Au-Sn metallization system is not only environmental-friendly composite without lead, but also exhibits desirable mechanical properties such as high strength and low thermal fatigue. These properties make eutectic AuSn solder an excellent choice for applications such as optoelectronic packaging and microwave device production. Conventional Au-Sn bonding process is reflow assembly. The eutectic Au80Sn20 (wt%) solder, with a melting temperature of 280C, is widely used in packaging applications. The high temperature induces to not only the degradation of bonding accuracy, the damage of components but also higher energy consumption and associated costs. In order to realization of high density package by Au-Sn flip chip structure, low temperature bonding method is developed by a surface activated bonding (SAB) method. Au-Sn can be bonded successfully at room temperature in vacuum, and 150C even in ambient air. The effective factors, such as bump configuration, surface activated process, bonding environment, bonding load and temperature, was investigated on the Au-Sn bonding by the SAB method. The bonding quality was checked by electrical resistance test and shear or tensile test. The bonding interfaces and fracture surfaces were observed by scan electron microscope (SEM) and electron probe micro-analyzer (EPMA).

    In this study, we examined surface activated bonding (SAB) of Si with sputtered Au electrodes that have different surface roughness. As surface activation process, argon low pressure plasma (physical process) and oxygen atmospheric pressure plasma (chemical process) were used, and bondabilities were evaluated. By irradiation with Ar low pressure plasma, Au-Au interface formed strong joint at low temperature (150&deg;C). In addition, samples that have small surface roughness formed connection at low temperature (150&deg;C) with oxygen atmospheric pressure plasma.

    これまで、表面活性化による半導体光素子の低温実装について研究を進めてきた。本研究では、接合条件が素子に与えるダメージを評価するため、接合温度や荷重を変化させながら接合した面発光レーザの光出力-電流-電圧特性を計測した。高温(330 ℃以上)や高荷重(1300 gf以上)で接合した素子では光出力の低下が観察され、それ以下の領域では接合強度等の機械的特性と合わせて最適な接合条件があることが確認された。

    This paper reports the results of low&ndash;temperature direct flip&ndash;chip bonding of a vertical cavity surface emitting laser (VCSEL) on a micromachined Si substrate. In direct bonding process at low temperature, we used the flip&ndash;chip bonder that utilizes the Surface Activated Bonding (SAB) method. Au electrodes of the VCSEL and Si substrate were cleaned by Ar radio frequency (RF) plasma irradiation, and Au&ndash;Au bonding was carried out in ambient air with applying static pressure. Strong die&ndash;share strength was obtained by bonding at 150&deg;C and emission from the VCSEL after the bonding was observed.

    Today telemedicine networks are evolving rapidly, so estimating mental and physical conditions of patients with accuracy and non&ndash;invasively is seen as important. However, estimation of the patient&prime;s blood flow volume is far from practical use in telemedicine networks, for that conventional sensors are badly large and expensive. Then we developed original integrated blood flow sensor and studied for practical use. As a result, we could extract the sympathetic components and palmic components of blood flow shifts from original signals that are proportional to blood flow volumes of fingertips. Former is affected by the patient&prime;s mental conditions, and latter is affected by heartbeat fluctuation.

    This paper reports the results of low&ndash;temperature flip&ndash;chip bonding of a vertical cavity surface emitting laser (VCSEL) on a micromachined Si substrate. Low temperature bonding was achieved by introducing surface activation by plasma irradiation into the flip&ndash;chip bonding process. After the surfaces of the Au electrodes of the VCSEL and Si substrate were cleaned using an Ar radio frequency (RF) plasma, Au&ndash;Au bonding was carried out only by contact in ambient air. At a bonding temperature of 100 &deg;C, the die&ndash;shear strength exceeded the failure criteria of MIL&ndash;STD&ndash;883.

    Integrated optical microsensors based on photolithography were developed in the early 1990s. Since then, sensors that make the most of the intrinsic properties of laser diodes have been developed. A marriage of micromachining and opto-electronics is expected to create tremendous new opportunities for applications. This article introduces various laser-based microsensors that can be incorporated into a small actuator fabricated by micromachining technologies, and laser-based sensors using microstructural elements (microbeans, microspheres, and microtips).

    Laser-driven assembly and angular alignment of micro-components (micro-lens and micro-prisms) have been demonstrated. This optically induced angular alignment results from the transfer of the angular momentum of the laser light due to the photon spin produced by the birefringence of the trapped micro-components. The fabricated components (retardation=0.76&lambda;) were made to align at desired angular positions by changing the direction of the vibration plane of the incident light. Continuous rotation was also possible by using a circularly polarized laser beam. Signal light control using optically driven micro-phase plate has also been demonstrated.

    We describe our recent activities for developing a large-scale 3-D MEMS optical switching fabric. The switches, consisting of MEMS 2-axis tilt mirror arrays and free-space optical interconnections, have great potential in the construction of large-scale switching fabrics with more than 1000 ports. The MEMS tilt mirrors that constitute the array are made of single-crystal silicon supported by a high-aspect-ratio torsion spring, and are controlled by terraced driving electrodes. The optical collimator arrays are comprised of two-dimensional optical fiber and polymer microlens arrays; the optical fiber arrays consist of optical fibers with micro-ceramic ferrules aligned in a polymer substrate having an array of precisely-aligned and positioned holes to fix the ferrules. A prototype switch having 64ch optical fiber I/O provides a low coupling loss of 3.2 dB and switching time of 14 msec.

    We have developed an optical passive algnment technique using alignment marks for hybrid integration. The hybrid integration of various optical components(laser diode, photodiode, grating, etc)on a silicon substrate(surface mounting)enables us to construct highly functional, reliable, and low-cost micro-sensors. Using this technique, several micro-sensors, including a high-resolution encoder that can measure the displacement or revolution angle, and a blood flowmeter that can monitor blood flow in human skin, have been developed. Because of their small size(2×3mm^2)with high performance, these sensors have a great potential for many industrial applications.

    A micro IC probe, which is a small, elastic electrical contact, has been developed to improve LSI testing and reduce its cost. No larger than 300×80 μm, it is fabricated with a pitch of 100 μm by micromachining techniques. Its contact resistance is less than 0.5 Ω, satisfying the requirements for conventional probes, and its deflection is 2 to 8 μm to accommodate height differences among LSI pads while maintaining contact.

    We developed a laser diode(LD)integrated with a polyimide waveguide on the same GaAs substrate to control(divide or collimate)the emitted light beam To divide the beam from the LD we fabricated a groove to act as a half-mirror in the polyimide waveguide. When the incident angle to the groove surface was a little below the critical angle at a suitable groove width, we obtained the half mirror effect. Additionally, to collimate the beam in the horizontal direction inside the polyimide waveguide we fabricated a parabolic-shaped total internal reflection mirror in the polyimide waveguide. The far field pattern(FFP)was measured to be 1.8°.

    Techniques to optically manipulate micrometer-sized dielectric particles have been used as optical tweezers in biological and chemical applications. We have extended the use of optical manipulation to study the rotational manipulation of dissymmetrically shaped micro-objects fabricated by micromachining. Principles and various characteristics of the optically induced rotations are reviewed and discussed.

    Using a newly developed, precise laser-microprocessing system of biological cells, we successfully observed a fusion of mouse myeloma cells. For this system, an XeCl excimer laser pumped dye laser was employed. The UV laser beam was carefully focused to about 1&mu;g in diameter on an intersection of contacted two cells to fuse.<BR>The cell fusion rate was found to depend on the laser pulse energy and the number of irradiated laser pulses. The maximum fusion rate of about 50% was observed under the condition of 30 pulse shots of 1.5&mu;J pulse energy and 10nsec pulse width. The viability of fused cells was confirmed by means of trypan blue dying.

    Indium is a favorable metal for solder due to its properties such as its low melting point of 156.6℃, good wettability, high ductility, good thermal conductivity, and high malleability. However, indium is extremely easy to oxidize. The effects of hydrogen radical treatment on indium surface oxide removal was conducted by spreading ratio test of indium balls, and it was found that hydrogen radical treatment longer than 20 s at temperatures higher than 170℃ results in successful surface oxide removal. X-ray Photoelectron Spectroscopy analysis was used to study the re-oxidation behavior after treatment, and it was found that hydrogen radical treatment slows down the re-oxidation of indium compared to surface oxide removal realized by physical bombardment of an argon fast atom beam. Based on these experimental results, we have developed indium bumping process which does not require cleaning of flux residue using non-residue indium solder paste and hydrogen radicals.

    Compact and high power semiconductor lasers are key components in various scientific and industrial instruments including laser displays and fluorescence analysis systems such as confocal microscopes and flow cytometers. The temperature rise of the active region in the high power semiconductor lasers strongly affects the threshold and output power characteristics and causes degradation of the lasers exponentially. Thus, efficient heat dissipation and thermal management are highly important. In this study, we have developed a direct bonding method and a bonding method using a smooth gold thin-film interlayer (root-mean-square roughness < 0.5 nm) for GaAs/SiC heterogeneous integration. The improved heat dissipation structure for high power semiconductor lasers was demonstrated in the wafer scale at room temperature.

    This research aims to establish a method for room temperature bonding in ambient gas as a new approach to industrial and volume production for devices using the surface activated bonding method which has been developed in advance in Japan. For thie purpose, the fundamental knowledge for bonding and it mechanism was accumulated and compiled systematically. Based on those research results, new processes including Ar-ion bombardment, Si-nano adhesion layer, atom diffusion bonding, air-plasma treatment, hydrogen radiacal treatment, and their combined process were proposed to demostrate the feasibility of the method for room temperature bonding. During the research also a new finding was done that shows the possibility of bonding polymers, glasses, and SiC using Si-Fe nano-adhesion layer, which was not planned in the original research proposal. Finally it has been shown that the proposed process can be applied successfully to integrating optical microsystems and sealing micro-devices.

    Basic concept by the results of marketing research and computer simulations of the elements of the sensing system, optical fiber system and the ideas for several sensor heads were developed. A MEMS vibrating sensor, temperature sensor, is excited by optical pulses from an optical fiber connected to a laser diode. The optical pulse frequency is tuned to the resonant frequency of the MEMS sensor. The resonant frequency of this vibrating sensor can reflect physical quantities such as temperature, pressure, and gas density. The main features of the sensing system are its ability to be used as an isolated sensor with no electronic circuit or power supply. At the last year (2010), the result of this research was reported at international conference, and the technical survey based international conferences were developed.

    Bonding of n-type GaN to gallium arsenide (GaAs) and polycrystalline Al was realized by surface activated bonding method at room temperature. The interface microstructure, bonding strength, and electrical characteristics of bonded interface junctions have been investigated through transmission electron microscopy (TEM), die-shear strength testing, tensile strength testing, and current-voltage (I-V) measurements. The silicon doped n-type GaN films used in this experiment were grown by metal organic chemical vapor deposition on (0001) sapphire substrates. For producing active surfaces, argon-fast atom beam (FAB) sputtering source (acceleration voltage and current of 1.5 kV and 15 mA) was used. The background pressure in the bonding chamber was in the range of 4×10^<-4>-6×10^<-7> Pa. The samples were brought into contact as quickly as possible at room temperature after surface activation. GaN films were successfully bonded to GaAs substrates and polycrystalline Al rods without any heat treatment. Cross-sectional TEM of GaN/Al samples bonded at room temperature showed a nearly continuous amorphous thin interlayer with a thickness of about 10 nm at the interface. The die-shear strength of GaN/GaAs was in the range of 1.5 -7 MPa. The tensile strength of GaN/Al was in the range of 14-19 MPa. The results of I-V measurements showed that the n-GaN/Al junctions without annealing were rectifying, and became ohmic after annealing in N_2 at 600℃. The advantage of our process is free from the various problems caused by the large thermal expansion mismatch during heat treatment in the conventional fusion bonding.

    A sequential plasma activation process is proposed to bond wafers of silicon and glasses at low temperature. The method is composed by oxygen plasma activation followed by nitrogen plasma activation. The effect of the surface activation on the bond strength and the bonding mechanism were investigated by using surface characterization. The bond strength increases with increasing the bonding temperature and the contents of OH group in the glasses does not affect the bond strength. The dependence of the bond strength on the plasma activation conditions was investigated quantitatively. The results of the characterization of the bonded interfaces using HRTEM show that there is an amorphous layer at the bonded interface which is induced by nitrogen radical irradiation, forming a kind of silicon oxynitride. As a new application of the proposed process, sapphire wafers were bonded to silicon at a temperature annealing as low as 300℃. No other method is known other than our proposal method for low temperature sapphire wafer bonding so far. Also the feasibility of low temperature wafer bonding of Lithium tantarate was demonstrated using the sequential plasma activation process at low temperature. The results show that a reliability enough high for industrial application such as SAW filters is achieved by bonding at low temperature in air, which fill the requirement of dicing the bonded wafers into 1 mm by 1mm pieces without delamination. Finally, a structure with microcavities was constructed by using the wafer bonding technique we propose in the present study. The tight sealing characteristic of the bonded interface was confirmed by a vacuum leak test.
