Abstract
Integrated circuits having doped bands in a substrate and beneath high-voltage semiconductor-on-insulator (SOI) devices are provided. In one embodiment, the invention provides an integrated circuit comprising: a semiconductor-on-insulator (SOI) wafer including: a substrate; a buried oxide (BOX) layer atop the substrate; and a semiconductor layer atop the BOX layer; a plurality of high voltage (HV) devices connected in series within the semiconductor layer; a doped band within the substrate and below a first of the plurality of HV devices; and a contact extending from the semiconductor layer and through the BOX layer to the doped band.
