Abstract:
A strain relaxed silicon germanium layer that has a low defect density is formed on a surface of a silicon substrate without causing wafer bowing. The strain relaxed silicon germanium layer is formed using multiple epitaxial growing, bonding and transferring steps. In the present application, a thick silicon germanium layer having a low defect density is grown on a transferred portion of a topmost silicon germanium sub-layer of an initial strain relaxed silicon germanium graded buffer layer and then bonded to a silicon substrate. A portion of the thick silicon germanium layer is then transferred to the silicon substrate. Additional steps of growing a thick silicon germanium layer having a low defect density, bonding and layer transfer may be performed as necessary.

Claim (Index 2):
The semiconductor structure of  claim 1 , wherein the strain relaxed silicon germanium layer has a germanium content from 20 atomic percent germanium to 25 atomic percent germanium.
