Patent ID: 7968358

Claim:
A method of manufacturing an imaging array comprising: providing a silicon tile having a first surface and a second, opposite surface and a dielectric layer in the silicon tile between the first and second surfaces, proximate the first surface to define a bottom silicon layer between the first surface and the dielectric layer; forming a separation boundary in the silicon tile between the second surface and the dielectric layer to define a top silicon layer between the dielectric layer and the separation boundary and a removable silicon layer between the separation boundary and the second surface; bonding the first surface of the silicon tile to an insulating substrate; separating the silicon tile at the separation boundary to remove the removable silicon layer, exposing the top silicon layer; and forming one or more semiconducting devices in one or more of the exposed top silicon layer, the dielectric layer and the bottom silicon layer, wherein the semiconductor devices comprise one or more photosensitive elements and one or more readout elements spaced from the one or more photosensitive elements, wherein forming the readout elements comprises removing the top silicon layer and the dielectric layer to expose the bottom silicon layer and forming the readout elements using the bottom silicon layer.
