Abstract:
1. A method for fabricating one or more devices, the method comprising: providing a substrate, the substrate having a thickness of semiconductor material and a surface region, the substrate also having a cleave plane provided within the substrate and defining the thickness of semiconductor material; joining the surface region of the substrate to a first handle substrate; initiating and propagating a controlled cleaving action at a portion of the cleave plane to detach the thickness of semiconductor material from the substrate, while the thickness of semiconductor material remains joined to the first handle substrate, to expose a second surface region of the thickness of semiconductor material; joining a backside of the first handle substrate to a second handle substrate; processing the second handle substrate with the thickness of semiconductor material using one or more processes to form at least one integrated circuit device onto a portion of the thickness of semiconductor material; forming a planarized surface region overlying the thickness of semiconductor material; joining the planarized surface region to a face of a third handle substrate; and removing the second handle substrate from the first handle substrate including the thickness of semiconductor material, while the face of the third handle substrate remains joined to the planarized surface region.
