Physically-Based Approach to Deep-Submicron MOSFET Compact Model Parameter Extraction

Chiah S.B., Zhou X., Lim K.Y., See A., Chan L., Nanyang Technological University, SG

This paper demonstrates a physically-based approach to parameter extraction of the compact Ids model we have developed for deep-submicron technology development. A two-iteration parameter-extraction scheme is described, which improves the previous one-iteration approach. Parameter calibration [...]

Compact Model for Manufacturing Design and Fluctuation Study

Lim K.Y., Zhou X., Chartered Semiconductor Manufacturing Ltd., SG

In this article, a physics based compact model [1, 2] has been used as a tool for manufacturing process variability study. Three critical end-of-line (EOL) measured electrical testing (ET) parameters, namely Vth, Ion and Ioff, [...]

Xsim: A Compact Model for Bridging Technology Developers and Circuit Designers

Zhou X., Nanyang Technological University, SG
