Abstract:
1. A method of forming a planar hybrid orientation substrate comprising: selecting a starting substrate comprising a first single crystal semiconductor layer having a first crystal orientation overlying a second single crystal semiconductor layer having a second crystal orientation different from the first, said first and second semiconductor layers separated by a sacrificial spacer layer; performing a selected area amorphization on one of said first or second semiconductor layers to form localized amorphized regions in said semiconductor layer; performing in-place bonding to bring said first and second semiconductor layers into direct contact at a bonded interface; and recrystallizing the localized amorphized regions across the bonded interface, using the semiconductor on the non-amorphized side of the bonded interface as a template, thereby changing the orientation of the semiconductor in the localized amorphized regions from its original orientation to a desired orientation.
