A 1M-pixel progressive-scan interline-transfer (IT) CCD image sensor has been developed. It features high resolution (1024 × 1024), real-timespeed (60 frame/sec) and square pixels (10μm × 10μm). A real-time speed was obtained by a pair of H-CCDs, located at the upper and lower of the image area and driven at 43MHz. Charges of the upper and lower halves of the image area are output separately by using the upper and lower H-CCDs, respectively. This operation enables a 1024 × 1024 progressive scan at 60 frame/sec. The device can be operated in a 512 × 512 progressive scan at 120 frame/sec by combining the charges in each of two vertically-adjacent pixels and two horizontally-adjacent pixels. Furthermore, a 1024 × 1024 interlace scan at 120 field/sec is also acceptable for either frame-integration or field-integration. The device can also be operated in a 1024 × 1024 progressive scan at 30 frame/sec by using only one of the H-CCD. © 1997 SPIE. All rights reserved.

A great effort has been underway in recent years to develop microwave and millimeter wave monolithic integrated circuit (MIMIC) technology for phased array radar systems for airborne and space based applications. solid-state MIMICs have made a dramatic impact on capability, reliability, and cost of these sensor systems. However, the computer-aided engineering (CAE) tools necessary for the modeling and simulation of such complex systems has not kept pace. This paper presents a methodology for the utilization of neurocomputing technology to achieve enhanced yield and efficient yield prediction in integrated circuit (IC) manufacturing. Specifically, artificial neural networks (ANNs) are employed to model complex relationships between material and device characteristics at critical stages of the semiconductor fabrication process. Additionally, a methodology for the development of ANN models of MIMIC passive elements based on the elements physical parameters is described. Results are presented which illustrate that a ANN can predict the equivalent circuit parameters (ECPs) and/or the scattering-parameters of these passive elements to nearly the same degree of accuracy as that afforded by electromagnetic (EM) simulation.

The interest in miniaturization of modern chemical and medical sensors is steadily increasing. However, when employing methods and fabrication procedures especially developed for microelectronics, one may encounter new and unpredictable problems for applications in aqueous media. For instance, in microelectronics often a dual metal layer system is employed for making electrical contacts. In a solution such a contact may result in galvanic reactions and/or may dissolve in the cleaning agents used for sterilization of medical devices. To address such issues we have employed an all-silicon based process technology for fabrication of sturdy and reliable devices with integrated poly-Silicon electrodes that tolerate most chemical environments. In this presentation we will report on the first results using such electrodes. A comparative study between identical poly-Si and Aluminium electrodes was made in order to investigate the usefulness of poly-Si electrodes. We will also demonstrate the nice possibility to use wall-documented methods for surface modifications using silane coupling chemistry. We believe this added benefit for the silicon based electrodes of easy surface modification processes, as compared with metal electrodes, to be extremely valuable for the development of accurate and tailored sensor structures for specific applications.

This paper proposes a new type of image sensor on which correlation detectors between incident lights and electronic signals are integrated as a 2-D array. This architecture is characterized by: 1) photodiodes for converting incident photons to currents (multiplicands), 2) one or a few external electric signals (multipliers) which are common to all pixels, 3) multipliers of the photo currents and the external signals, 4) capacitors for accumulating the products as the correlation results, and 5) CCD or MOS switching networks for scanning out the correlation results. Several design and applications of the sensor are demonstrated.

Laser Radar Technology and applications II

NASA's Marshall Space Flight Center has developed an active sensor system, the ideo guidance sensor (VGS), to provide near-range relative position and attitude data. The VGS will be part of an automatic rendezvous and docking system. The VGS determines the relative positions and attitudes between the active sensor and the passive target. It works by using laser diodes to illuminate the retro-reflectors in the target, a solid-state camera to detect the return from the target retro-reflectors, and a frame grabber and digital signal processor to convert the video information into relative positions and attitudes. The current sensor design is the result of several years of development and testing, and it is being built to fly as an experiment payload on the space shuttle. The VGS system is designed to operate with the target completely visible within a relative azimuth of ± 10.5 degrees and a relative elevation of ± 8 degrees. The system will acquire and track and target within that field-of-view anywhere from 1.0 meters to 110 meters range at any relative roll angle and relative pitch and yaw attitudes of up to ± 10 degrees. The data is output from the sensor at 5 Hz, and the target and sensor software have been designed to permit two independent sensors to operate simultaneously for redundancy.

Self sharpening tips have been integrated on arrays of cantilevers provided with self exciting piezoelectric sensors (ZnO) by using monocrystalline silicon micromachining. Atomic force microscopy (AFM) images of grids with periods of 0.25 /spl mu/m, 1 /spl mu/m and 5 /spl mu/m and with height differences of 100 nm, 15 nm and 180 nm respectively have been achieved with single cantilevers.

International Conference on solid state sensors and Actuators (TRANSDUCERS)

作者： J. Mitrovics H. Ulmer G. Noetzel U. Weimar W. Gopel Institute of Physical and Theoretical Chemistry Center of Interface Analysis and Sensors University of Tübingen Tubingen Germany

We present a new very flexible design of a sensor system for gas and odor analysis, which may easily be optimized for specific applications. The core part contains a digital bus system that connects individual sensor modules with a central processor. By using dedicated microcontrollers onboard the modules it is possible to use any kind of transduction principles ("hybrid system"), with typical numbers of individual sensor elements for each transducer of the order of 8, as well as actuators. The measured sensor parameters are transmitted via a standard protocol on the digital bus system, hence all types of modules are interchangeable. This allows an easy adaption of new technologies to new applications. The specifications of the interface are available to developers and researchers, thus offering them the possibility to introduce their own specific technologies for certain applications. The system allows one to combine self made sensors with a growing range of other available technologies and can thus be used as a benchmarking tool.

By focusing on the sophisticated functions of the mammalian cochlea, we are aiming to apply its resonator array structure to highly efficient smart sensors and actuators. In this paper, we propose an equivalent mechanical model named "fishbone architecture" which is easily realized by Si micromachining. applications of the architecture to a sensor-artificial basilar membrane (BM) microphone (ABMM)-and an actuator-"giant impulse generator"-are proposed and examined by FEM analyses. The fabrication process and experimental results of the Si device are shown.

Signal Evaluation of Gas sensors with Artificial Neural Nets

IFAC Proceedings Volumes 1997年第7期30卷 363-368页

Due to the lack in selectivity and separability of most common gas sensors, the use of sensor arrays together self adapting systems as artificial neural nets (ANN) is necessary. These systems can evaluate the gas concentration or deliver a binary signal (gas present or not, ventilation on or off, etc.), which gives a chance to solve measurement problems in gas mixtures. Also the estimation of indoor air quality, olfactometric measurements, etc. may be possible using ANN methods. A promising new approach is the use of non-stationary (transient) signals of a single sensor after a certain stimulus (i.e. a temperature change, etc.). This additional information enhances the redundancy of such a system and a single sensor delivers further information (virtual sensor array). Signal evaluation methods for chemical sensors are powerful tools, they are adaptable to specific applications and are compatible to customary micro controllers.

A people counting system with human information sensors for use in a multi-sensing application for detecting the number of persons and their directions of movement at a wide door has been developed. The sensor head module of this sensing system consists of a 1-dimensional 8-element detector array fabricated by a sheet forming method of pyroelectric PbTiO/sub 3/ ceramics, a IR-transparent lens and oscillating mechanical chopping parts. The sensor output is binarized by using the background mean method, and the number of passing persons and their directions of movement are recognized by a pattern recognition algorithm. By using this people counting system, the number of passersby at a 200 cm wide door can be detected with more than 95% accuracy.
