Abstract: A process includes depositing an edge fill dielectric over a first workpiece and a device disposed thereon. The edge fill dielectric is patterned so that only the edge portions remain. A second dielectric material is formed over the first workpiece, device, and edge fill dielectric. A planarization process levels the second dielectric material and the device. A bonding layer is formed thereon and a second workpiece bonded thereto by a dielectric-to-dielectric bond.

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.
