Patent ID: 8236636

Claim:
A method of forming a hybrid semiconductor structure having at least two coplanar regions of different surface orientations and having reduced boundary defects comprising: providing a bilayer template stack comprising a direct semiconductor bonded (DSB) silicon layer of a (011) surface orientation disposed on a base silicon layer having a (001) surface orientation, wherein an in-plane <110> direction of the DSB silicon layer and an in-plane <110> direction of the base silicon layer are aligned to be parallel; implanting amorphizing ions into selected regions of the DSB silicon layer to amorphize said selected regions down to said base silicon layer, leaving original-orientation regions of the DSB silicon layer in regions not so implanted, wherein edges of said selected regions are aligned with in-plane <100> directions of the base silicon layer; and performing a recrystallization anneal to convert said amorphized selected regions into changed-orientation regions having the (001) surface orientation of the base silicon layer, wherein edges of said changed-orientation and original-orientation silicon regions are separated by a near-vertical boundary in a boundary region.
