Title: Innovations by Brian McFarlane
Introduction
Brian McFarlane is a notable inventor based in Campbell, CA (US). He has made significant contributions to the field of semiconductor technology, holding a total of 5 patents. His work primarily focuses on enhancing the performance and reliability of electronic devices.
Latest Patents
One of McFarlane's latest patents is for a transistor device with increased breakdown voltage. This bipolar lateral device is designed to have a high BV.sub.ceo, formed through a single polysilicon process. In one embodiment, silicide is excluded from the surface of the N+ doped polysilicon, protecting the N- base width region, resulting in a BV.sub.ceo of 8 to 10 V. In another embodiment, the polysilicon is maintained as intrinsic, achieving a BV.sub.ceo of about 20 V. These devices are particularly useful as voltage clamping devices in programmable logic circuits that require a collector to emitter reverse bias voltage sufficient to program either vertical or lateral fuse devices.
Another significant patent involves a vertical fuse structure that includes a lightly-doped shallow emitter, which enhances fusing characteristics. This structure features a buried collector, an overlying base, and an emitter above the base. The emitter extends about 0.2 microns from the upper surface, with a dopant concentration of approximately 8.times.10^19 atoms of arsenic per cubic centimeter at the surface. The design allows for improved programming of the fuse through the shorting of the emitter.
