Abstract:
1. A method of forming of a semiconductor structure on a semiconductor-on-insulator substrate, the semiconductor-on-insulator substrate comprising a handle wafer, a buried oxide (BOX) layer on top of the handle wafer, and a top silicon layer on top of the BOX layer, the method comprising: forming a shallow trench isolation region in the top silicon layer; implanting the top silicon layer with a noble gas to form an implantation region in the top silicon layer; and forming one or more semiconductor devices in the implanted top silicon layer, wherein forming one or more semiconductor devices in the implanted top silicon layer comprises forming an n-well and a p-well of a PiN junction, and wherein the implantation region extends across the n-well, an intrinsic silicon region, and the p-well of the PiN junction.
