Research Abstract |
The purpose of this research project is to establish the basis of "brain and nerve in 21 st century's wireless multimedia." 1. Nano-meter MOS device physics Research and development of 0.1um MOSFET process technology have been investigated. Breakdown phenomena of ultra-thin gate oxide were evaluated in relation to reliability. Furthermore, diffusion model of dopant in a shallow junction were proposed. These results are going to be adopted in TCAD system. 2. Flexware system Flexible functional four-terminal neu-MOS devices, vector quantization processor, most-significant- digit-first calculation scheme, have been developed for real-time motion picture compression. As a result, it is shown that ITOPS/1W processor, whose calculation power is 20,000 times as much as conventional one, can be realized. 3. Optical wiring parallel processing LSI chip For aiming optical wiring high-speed pattern recognition chip, a design method for optical wiring, a fabrication process for optical wiring, and integration technologies for light emission/receiver devices have been developed. Design and implementation methods for integrated optical waveguides have been established. 4.Highly reliable SS-CDMA wireless communication system Gigahertz-band wireless multimedia information terminal has been investigated. For downlink access ; from basestation to handy terminal, packet SS-CDMA scheme using 2.46Hz front-end AIN SAW matched filter has been developed. For uplink access ; from terminal to basestation, approzisately-synchronized SS-CDMA cellular system using SAW convolver has been developed. CDMA channel number of 64ch/voice-rate is successfully oobtained in a 150m-radius cell.
