    摘要: The present invention provides a method for manufacturing a semiconductor device. In one embodiment, the method for manufacturing the semiconductor device includes a method for manufacturing a zener diode, including among others, forming a doped well (240) within a substrate (210) and forming a suppression implant (420) within the substrate (210). The method for manufacturing the zener diode may further include forming a cathode (620) and an anode (520) within the substrate (210), wherein the suppression implant (420) is located proximate the doped well (240) and configured to reduce threading dislocations.

    摘要: A junction field-effect transistor (JFET) includes a substrate having a first-type semiconductor surface including a topside surface, and a top gate of a second-type formed in the semiconductor surface. A first-type drain and a first-type source are formed on opposing sides of the top gate. A first deep trench isolation region has an inner first trench wall and an outer first trench wall surrounding the top gate, the drain and the source, and extends vertically to a deep trench depth from the topside surface. A second-type sinker formed in semiconductor surface extends laterally outside the outer first trench wall. The sinker extends vertically from the topside surface to a second-type deep portion which is both below the deep trench depth and laterally inside the inner first trench wall to provide a bottom gate.
