Abstract:
A method of manufacturing a semiconductor device, comprising the steps of:providing a silicon-on-insulator semiconductor wafer having a silicon film formed on an insulator layer; forming at least one semiconductor device in the silicon film, the at least one semiconductor device including an active semiconductor element, an interlayer dielectric over the semiconductor device, and at least one opening passing through the interlayer dielectric and in communication with the active semiconductor element; implanting inert atoms into one or more of the active semiconductor clement by passing the inert atoms through the opening at an energy and at a dose sufficient to form a damaged region in the active semiconductor element, wherein the interlayer dielectric acts as a mask to block implantation of the inert atoms into other portions of the semiconductor device, and the damaged region comprises gettering sites; and subjecting the semiconductor device to conditions to getter at least one impurity into the gettering sites from adjacent portions of the semiconductor device.
