Abstract: In accordance with an aspect of the invention, A Schottky junction field effect transistor (JFET) is created using cobalt silicide, or other Schottky material, to form the gate contact of the JFET. The structural concepts can also be applied to a standard JFET that uses N? type or P? type dopants to form the gate of the JFET. In addition, the structures allow for an improved JFET linkup with buried linkup contacts allowing improved noise and reliability performance for both conventional diffusion (N? and P? channel) JFET structures and for Schottky JFET structures. In accordance with another aspect of the invention, the gate poly, as found in a standard CMOS or BiCMOS process flow, is used to perform the linkup between the source and the junction gate and/or between the drain and the junction gate of a junction filed effect transistor (JFET).

Abstract: NPN and PNP bipolar junction transistors are formed in a semiconductor substrate material in a double polysilicon CMOS process flow in a manner that allows the collectors of both of the npn and pnp bipolar transistors to be biased differently than the bias that is placed on the semiconductor substrate material.

Abstract: The collector resistance of a bipolar junction transistor that is formed in a CMOS process is substantially reduced by forming a heavily-doped collector extension region that extends from a heavily-doped collector contact region down to a deep well of the same conductivity type to a point that lies close to the base of the transistor.

Abstract: A method is provided for obtaining extremely fine pitch N-type and P-type stripes that form the voltage blocking region of a superjunction power device. The stripes are self-aligned and do not suffer from alignment tolerances. The self-aligned, fine pitch of the alternating stripes enables improvements in on-state resistance, while ensuring that the superjunction device is fully manufacturable. Only one masking step is required to fabricate the alternating N-type and P-type stripes.

Abstract: An improved NPN bipolar transistor integratable with CMOS FET processing is achieved. The transistor is formed on a substrate using a CMOS process and one additional masking and implant step. The CMOS N wells are used to form the collector contacts (reachthrough) and the P wells are used to form the base. N doped third wells are formed under the N wells, P wells, and shallow trench isolation regions to provide subcollectors. Since the P wells are not implanted through the STI, basewidths are reduced and current gain is increased. Gate electrode masking elements, formed over the base, separate the emitter and base contact regions, improving the emitter-to-base breakdown voltage. The CMOS source/drain N type implants then form emitters in the emitter regions and ohmic contacts in the collector contacts. The source/drain P type implants form the ohmic base contacts to complete the bipolar transistor.

Abstract: A method for forming a thin film, electrically blowable fuse with reproducible blowing wattage using a sacrificial metal patch over a fuse dielectric layer and two etch processes; wherein the first etch process is selective to the metal patch and the second etch process is selective to the fuse dielectric layer. A fuse element, having an element width, is formed over a semiconductor structure, and a fuse dielectric layer is formed over the fuse element. A sacrificial metal patch is formed on the fuse dielectric layer; wherein the patch width being greater than the fuse element width. A second dielectric layer is formed on the sacrificial metal patch, and additional metal layers and dielectric layers may be formed over the second dielectric layer, but only the dielectric layers will remain over the fuse element.
