The Computer Device Laboratory, the CDL, focuses on education and research on VLSI technology, devices, and their related area. The main activities are as follows:

1. Education:
   • Physics of Semiconductor Devices
   • Microelectronics: Analog and Digital Circuit Technology
   • VLSI Design: Device/Prcoess Design & VLSI architecture

2. Research: The main objective of the research in the CDL is to develop a new environment for VLSI design and diagnoses. That will be an intelligent manufacturing system for VLSIs including a statistical representation, a topographic representation, and an expert system representation of VLSI design and diagnoses. And the objects of representation are not restricted in the devices and processing technologies, but will cover from the manufacturing system modeling to the reliability of VLSI. The research projects being performed in the CDL are as follows:
   • Research on Parameter Extraction for VLSI Simulation; with NTT LSI Laboratories
   • Research on ULSI Design Education System; with universities
   • Research on the Precise Modeling for T-CAD; with two laboratories from NTT, companies, and universities
   • Optimization of Resources for VLSI Production; with a VLSI company at Aizu-Wakamatsu
   • The universal Test Boards for VLSI Packages; with a VLSI company at Aizu-Wakamatsu

Prof. Kazuyuki Saito: In these ten years, his research interest is going toward the computer integrated manufacturing system. His understanding of CIM is the Centralized Information Manufacturing. On this concept, he developed a novel VLSI yield modeling applying to the Yield Enhancement, a novel Topography Simulator, a Factory Modeling using Queuing System, a Local Area Network in the VLSI Factory and its Application on the Quality Enhancement of VLSI production. He is now developing a Production Scheduling System with a novel algorithm.

Prof. Kenichi Kuroda: Before joining this university, he has been engaged with the x-ray lithography project using a synchrotron radiation source at NTT. He keeps his interest in design of X-ray mirror system which is expected to be used for X-ray lithography in future ULSI production. He has been developing a useful optimizing tool for the mirror system design. After joining the CDL, he is also interested in the multiple-valued logic devices such as neuron MOS, quantum devices, and other devices. These devices are expected to solve the complexity crisis in future ULSI circuitry.

Prof. Yasuhiro Hisada: His interest is computer simulation of semiconductor crystal growth process. The quality and yield of LSI is influenced quality of semiconductor crystal. He is also interested in biometrics. Now, he has been developed measurement and analysis system of a living body signal. This research is related to research of LSI for signal processing and analog circuit and sensor. In addition, this research will become the base of ultimate interface between computer and human.
