Beschreibung
Zusammenfassung:	Method and Apparatus so configured for the fabrication of three-dimensional integrated devices. A crystalline substrate within an area of a donor semiconductor wafer is etched. The substrate side is located opposite a device layer and has a buried insulating layer and a substrate thickness. The etching removes at least a substantial portion of the crystalline substrate within the area such that the device layer and the buried insulating layer in the area is to conform to a pattern specific topology on an acceptor surface. The donor semiconductor wafer is supported with a supporting structure that allows the donor semiconductor wafer to flexibly conform to the pattern specific topology within at least a portion of the area after the etching to enable conformality and reliable bonding to the device surfaces of an acceptor wafer to form a three dimensional integrated device.
