R&D Facilities and Capabilities

 

 Setting up Platform for IC Process Technology and Development

A 1-1.5m level VLSI Pilot Line was first established in IMETU in 1989 in China . There are about 1000 square meters clean rooms with different class of cleanness in it. Supported by national special construction funds, the line has been upgraded to 0.6~0.8m feature size VLSI Pilot Line. Cooperating with IBM Co. and Motorola Co., the Pilot Line is equipped with a complete set of sub-micron VLSI processing equipments. It has passed ISO9001 recognition of production quality. The output production capacity has reached more than 4500 wafers per month in 2004. The processing line has passed ISO9001 recognition of production quality and started to provide foundry service for industry. The pilot foundry also developed EEPROM、 FLASH、 high voltage 、 low power and SiGe new technology. This Pilot Line is open for nationwide use and serves as ‘the Multi-project Wafer Supporting Center' (MPW). Through introducing and digesting advanced IC technology from abroad, new technology and products for market will be studied and developed here. The Pilot Line is a platform for R&D and transformation of scientific achievements to universities, institutes and companies all over the country. It is a base to educate engineers and scientists in the IC technology field.

 

 Microelectronics Engineering Center

In December 2004, VLSI Pilot Line cooperated with China Electronics Corporation and invested 9.5M USD to establish the Microelectronics Engineering Center, which aims at the advanced research, fabrication and service of microwave SiGe HBT, SiGe ICs, special application ICs and non-volatile semiconductor memory ICs. Based on micro-electronics institute integrated circuit development and pilot line, the engineering center with investment 78 millions will conduct special silicon IC 、 SiGe HBT development and accomplish batch production.

 

  Electronic System Integration and IC Design Environment

The Electronic System Integration and ASIC Technology Research Center of Tsinghua University is one of the three research platforms of the IMETU. Based on Microelectronics Institute, the center was established and put into operation in 1997, passed certification in Oct. 1999. With IMETU as its research base, the group has floor space of 1100 square meters. It offers complete and advanced multilevel hardware and software environment for design, simulation and validation of processing and IC design. It is equipped with more than 50 workstations and 100 packages of front/back-end advanced IC design software. This is an open center to support research on electronic systems, design of ASIC system integration, developing joint research projects. It is also an education base for high quality scientists and engineers and a base for developing ASIC and EDA software.

 

Main Mumber of Micro-Nanoelectronic Processing Technology Research Center of Tsinghua Univ.

A research and fabrication center of Micro/Nano technology has been set up at IMETU with funding from Ministry of Education, 211 Grant. It is a base for design, fabrication and testing of Micro/Nano technology, which is the first one established in China. With its 1μm IC processing line and a set of three-dimensional silicon micron mechanical equipments, it can provide perfect lab services for research and fabrication of MEMS chips. High-level MEMS devices and technology have been developed in the lab. Many excellent papers have been published in academic journals both in China and internationally. A biochip research and fabrication base has been established at IMETU.
