Patent ID: 8241996

Claim:
A method for manufacturing multi-layered substrates, the method comprising: providing a handle substrate, the handle substrate having a first deflection characteristic, the handle substrate having a backside and a face; providing a donor substrate comprising a cleave region, the thickness of material, and a surface region, the cleave region being within the donor substrate to define a thickness of material, the thickness of material being provided between the cleave region and the surface region; bonding the surface region of the donor substrate to the face of the handle substrate; coupling a backing substrate to the backside of the handle substrate, the backing substrate being adequate to cause the first deflection characteristic of the handle substrate to be reduced to a predetermined level, the predetermined level being a suitable deflection characteristic for a thickness of material to be transferred onto the face of the handle substrate while the backing substrate remains intact to the handle substrate to maintain at least the suitable deflection characteristic; and initiating a controlled cleaving process within a portion of the cleave region of the donor substrate to begin removal of the thickness of material from the donor substrate at a portion of the cleave region.
