Latest Patents
Mitsuoka's latest patents include a groundbreaking semiconductor device that features a bipolar junction transistor with a protected emitter-base junction. This innovative method of manufacturing a CMOS-BJT semiconductor device involves several key steps. It begins with forming a collector region of a first conductivity type and a first well of the same type simultaneously in a semiconductor substrate. Next, a second well of a second conductivity type, which is opposite to the first, is formed in the substrate. A base region of the second conductivity type is then created within the collector region. The process continues with the formation of first and second insulated gate structures on the respective wells, along with a junction protection structure that shares the same constituent elements as the insulated gate structures on the base region. Finally, second source/drain regions of the first conductivity type are formed in the second well, and an emitter region of the first conductivity type is established in the base region, ensuring that the emitter-base junction reaches the principal surface beneath the junction protection structure.
