Latest Patents
One of his latest patents is a method for fabricating a super self-aligned bipolar transistor. This invention relates to a manufacturing process that allows for miniaturization of elements while simplifying the steps involved. The method employs a selective collector epitaxial growth process, eliminating the need for a trench to isolate elements. Isolation is achieved using a mask that defines the emitter region and a second spacer. The base layer features a multi-layer structure composed of silicon, undoped silicon-germanium, and p-type doped silicon-germanium. This innovative approach reduces the likelihood of leakage current and short effects between the emitter, base, and collector.
Another notable patent is the method for fabricating a lateral collector structure on a buried oxide. This invention provides a collector device within a bipolar device that features a lateral collector structure situated on a buried oxide layer. The design allows for high breakdown voltage, enabling high power operation at increased speeds. The buried collector is isolated from the substrate by a buried oxide film, which connects horizontally to the collector.
