Abstract: A composite wafer may be provided by: forming a layer stack including a carrier layer, an ion implantation layer, and a transfer material layer by implanting ions into a donor wafer; forming intersecting trenches through the transfer material layer, the ion implantation layer, and an upper portion of the carrier layer; attaching the layer stack to an acceptor wafer including a stack of a handle substrate and a first dielectric oxide layer by bonding the layer stack to the first dielectric oxide layer; and cleaving the layer stack at the ion implantation layer, whereby a composite wafer including the acceptor wafer and patterned portions of the transfer material layer is formed.

Abstract: Optical devices and methods of manufacture are presented in which a non-linear material is deposited or otherwise placed. Once the non-linear material has been deposited, implantation regions are formed within the non-linear material using an implantation process. The implantation regions are removed using an etching process, and electrodes are formed to the remaining material.

Abstract: A semiconductor device includes a first semiconductor die and a second semiconductor die connected to the first semiconductor die. Each of the first semiconductor die and the second semiconductor die includes a substrate, a conductive bump formed on the substrate and a conductive contact formed on the conductive bump. The conductive contact has an outer lateral sidewall, there is an inner acute angle included between the outer lateral sidewall and the substrate is smaller than 85°, and the conductive contact of the first semiconductor die is connected opposite to the conductive contact of the second semiconductor die.

Abstract: A package structure includes a circuit substrate, a semiconductor device, a plurality of cooling pins, a cooler lid, an anti-fouling coating and a top lid. The semiconductor device is disposed on and electrically connected to the circuit substrate. The cooling pins are disposed on the semiconductor device.
