0.12 μm raised gate/source/drain epitaxial channel NMOS technology

Abstract

We introduce a 0.12 /spl mu/m nMOS technology with multi-Vth's for mixed high-speed digital and RF-analog applications. Though basically device parameter was determined by SIA roadmap, new structures such as undoped epitaxial channel and raised gate/source/drain were applied to a 0.12 /spl mu/m nMOS. This device has high fT and low noise figure which are very important for RF analog circuit design. High Idrive/Ioff ratio for drain current was also realized.
