Bio-MEMS technology for DNA and Cell signal detection

This project is to develop IC based technology to interact with biological material. The technology can be used in Lab-on-a-chip technology to extract cell contents and detect the existance of certain DNA fragment. In addition non-invasive cell based technology to extract cell level signa for drug profiling is also being pursued.

Nano-CMOS Transistor Design & Fabrication

The objective is to design and fabricate of CMOS based nano-wire transistors using top-down manufacturing approach (in contrast to the bottom-up self-assembly approach developed by Chemist and Physicists) to extend the scalability of CMOS technology according to the ITRS Roadmap. The challenge in this project is the method to form extremely small lines with the limited capability available in our lab. We have been studing possible approaches such as oxide trimming, continuous oxidation and hydrogen annealing to form the silicon nano-wire transistor.

CMOS Compatible non-volatile technology for RFID

Embedded Non-volatile memory (NVM) is important to store data in RFID. However, most NVM technology required extract mask and processing steps in addition to standard CMOS technology. To fulfill the low cost requirement dictated by the RFID application, we are developing zero-mask embedded NVM technology and circuit based on standard CMOS processes.

Phase-Change Memory Characterization and Modeling

This is a sponsored project by IBM to study and model the driving device characteristics at the 45nm technology. Studies include diode circuit, double gate, multiple-gate and surrounding gate MOSFETs.

Multi-gate CMOS Device Modeling

This project is sponsored by NEDO, Japan to develop a compact model for multi-gate MOSFETs. The model include both the intrinsic devices and parasitic effects. The complete model will be implemented in Verilog-A code and release to the public . This is a join project with Hiroshima University and Peking University.
