摘要:
The present invention relates to a method (100) for forming a strained semiconductor structure (212, 312). The method comprises providing (102) a strain relaxed buffer layer (204), forming (104) a sacrificial layer (206, 306) on said strain relaxed buffer layer (204), forming (106) a shallow trench isolation structure (208) through said sacrificial layer (206, 306), removing (108) at least a portion (210) of an oxide layer on said sacrificial layer (206, 306), etching (110) through said sacrificial layer (206, 306) such that a portion of said strain relaxed buffer layer (204) is exposed (110), forming said strained semiconductor structure (212, 312) on said exposed portion (210) of said strain relaxed buffer layer (204).
