Abstract: A method of forming a germanium-on-insulator (GOI). An epitaxial germanium layer is formed on top of a first substrate. A first dielectric film is formed on top of the epitaxial germanium layer. A second substrate is provided. The first substrate is bonded to the second substrate by bonding the first dielectric film to the second substrate. The bonding resulted in a bonded wafer pair. The first substrate is removed after the bonding to expose epitaxial germanium layer to form the GOI substrate.

Abstract: An embodiment of the present invention is a technique to provide heat extraction for semiconductor devices. At least a thermoelectric film is fabricated onto a bare wafer. The backside of the bare wafer is bonded to an active wafer having at least a device. The bonded bare and active wafers are annealed.

Abstract: More complete bonding of wafers may be achieved out to the edge regions of the wafer by constrained bond strengthening of the wafers in a pressure bonding apparatus after direct wafer bonding. The pressure bonding process may be accompanied by the application of not above room temperature.

Abstract: A layer transfer technique in which a portion of a donor wafer is doped with positively charged hydrogen ions and positively charged helium ions before it is bonded to a portion of a handle wafer. Furthermore, the bonded wafers are annealed at one of two annealing temperatures, which determines whether the wafers are separated using a thermal cleave or a mechanical cleave process.

Abstract: Methods of forming a germanium on insulator structure and its associated structures are described. Those methods comprise forming an epitaxial germanium layer on a sacrificial silicon layer, removing a portion of the epitaxial germanium layer, activating the epitaxial germanium layer and an oxide layer disposed on a silicon substrate in an oxygen plasma, and bonding the epitaxial germanium layer to the oxide layer to form a germanium on insulator structure.

Abstract: A method of bonding a germanium (Ge) wafer to a semiconductor wafer. A Ge wafer having a cleaving plane defined by ion implantation is provided. A surface activation on at least one surface of the Ge wafer is performed. A semiconductor wafer is provided. A surface activation on at least one surface of the semiconductor wafer is performed. The Ge wafer is bonded to the semiconductor wafer to form a bonded wafer pair. A first annealing is performed to the bonded wafer pair. The first annealing occurs at a temperature approximately between 50-100° C. A second annealing is performed to the bonded wafer pair. The second annealing occurs at a temperature approximately between 110-170° C. The second annealing cleaves the Ge wafer at the cleaving plane.
