Method for forming strained layer with high Ge content on substrate and semiconductor structure

摘要

A semiconductor structure and a method for forming the same are provided. The semiconductor structure may comprise a substrate (110); an insulation layer (120) formed on the substrate (110); a strained layer (130) formed on the insulation layer (120); a strained layer (140) with high Ge content formed on the strained layer (130); and a gate stack (160) formed on the strained layer (140) with high Ge content.
