Latest Patents
One of Joyce's latest patents is the "Retrograde NWell cathode Schottky transistor and fabrication process." This invention presents an improved Schottky transistor structure that incorporates a bipolar transistor structure and a Schottky diode structure. The process involves retrograde diffusion of fast-diffusing atoms to create a localized retrograde diode well, which serves as the substrate for the Schottky diode structure. Additionally, an expanded buried collector layer formed of slow-diffusing atoms underlies the base and collector regions of the bipolar transistor structure. This innovative approach allows for the simultaneous formation of the buried diode layer and the buried collector layer during the fabrication process.
Another significant patent is the "Process for fabricating lateral PNP transistor structure and BICMOS IC." This patent describes a method for fabricating a lateral PNP transistor structure within a BICMOS process, utilizing the same steps as those used for NPN and CMOS transistors. The process is designed to streamline production without requiring additional steps, thereby enhancing efficiency in semiconductor manufacturing.
