Abstract
The suppression of short channel effect in strained-Si surface channel PMOSFET with carbon incorporation on relaxed SiGe buffers is demonstrated. The lateral diffusion of boron from source/drain into the channels is retarded by a reduction of interstitial formation due to carbon incorporation in the strained-Si layer. It is necessary to avoid the high temperature (>900 °C) process for SiC precipitations as trap centers which are observed by atomic force microscope and X-ray diffraction. An incorporated carbon in the source/drain is not only being stressor but also improves short channel effect for extremely shallow junctions, and makes it possible to have high speed devices.
