摘要:
A MOSFET structure utilizing strained silicon carbon alloy and fabrication method thereof. The MOSFET structure includes a substrate, a graded SiGe layer, a relaxed buffer layer, a strained silicon carbon alloy channel layer, a gate dielectric layer, a polysilicon gate electrode (or metal gate electrode) and a source/drain region.
