The transistor which possesses the distortion channel territory which includes performance strengthening material constitution

摘要

By forming a semiconductor alloy in a silicon-based active semiconductor region prior to the gate patterning, material characteristics of the semiconductor alloy itself may also be exploited in addition to the strain-inducing effect thereof. Consequently, device performance of advanced field effect transistors may be even further enhanced compared to conventional approaches using a strained semiconductor alloy in the drain and source regions.
