Publication number: 20100059819Abstract: A metal source power transistor device and method of manufacture is provided, wherein the metal source power transistor having a source which is comprised of metal and which forms a Schottky barrier with the body region and channel region of the transistor. The metal source power transistor is unconditionally immune from parasitic bipolar action and, therefore, the effects of snap-back and latch-up, without the need for a body contact. The ability to allow the body to float in the metal source power transistor reduces the process complexity and allows for more compact device layout.Type: ApplicationFiled: August 20, 2009Publication date: March 11, 2010Applicant: SPINNAKER SEMICONDUCTOR, INC.Inventor: John P.
