METHODS FOR MANUFACTURING A HIGH VOLTAGE JUNCTION FIELD EFFECT TRANSISTOR USING A HYBRID ORIENTATION TECHNOLOGY WAFER

摘要

Methods for manufacturing a high voltage junction field effect transistor. The method includes forming an opening extending from a top surface of a device layer of a hybrid orientation technology (HOT) wafer through the device layer and an insulating layer to expose a portion of a bulk layer, and filling the opening with epitaxial semiconductor material having the crystalline orientation of the bulk layer. The method further includes forming first and second p-n junctions in the epitaxial semiconductor material that are arranged in depth within the epitaxial semiconductor material between the second semiconductor layer and the top surface of the first semiconductor layer.
