Patent ID: 7642197

Claim:
A method of making an embedded silicon germanium (eSiGe) CMOS device comprising: providing a direct semiconductor bonded (DSB) silicon substrate comprising a first layer having a (100) oriented surface bonded to a second layer having a (100) oriented surface, wherein a <110> direction of the first layer is approximately aligned with a <100> direction of the second layer; performing amorphization on a selected region of the first layer to form a localized amorphous silicon region extending at least up to an interface of the first layer and the second layer; recrystallizing the localized amorphous silicon region across the interface using the second layer as a template, such that the <100> direction of the first layer in the selected region is approximately aligned with the <100> direction of the second layer; and forming an embedded silicon germanium layer along the <110> direction in the first layer of the direct semiconductor bonded (DSB) silicon substrate.
