摘要: Maskless etching of polysilicon is accomplished by exposing portions of a polysilicon surface to ion bombardment. Bombardment by oxygen or hydrogen ions is effective to reduce the etch rate of polysilicon in a chlorine-containing plasma. Therefore, patterned ion bombardment prior to etching in a chlorine plasma is effective to pattern the polysilicon surface.

摘要: A method of providing a Transient Voltage Suppression (TVS) device is described utilizing a Metal Oxide Semiconductor (MOS) structure and an Insulated Gate Bipolar Transistor (IGBT) structure. The MOS based TVS devices offer reduced leakage current with reduced clamp voltages between 0.5 and 5 volts. Trench MOS based TVS device (72) provides an enhanced gain operation, while device (88) provides a top side drain contact. The high gain MOS based TVS devices provide increased control over clamp voltage variation.
