Latest Patents

Sugiura's latest patents focus on sophisticated semiconductor manufacturing techniques. One of his key inventions is the "Method of manufacturing a semiconductor device comprising a bipolar transistor and a variable capacitor." This innovation details a variable capacitor consisting of an N layer that includes a variable capacitance region, alongside a P layer that is epitaxially grown on the N layer. The P layer is formed from a SiGe film and a Si film, complemented by a P-type electrode. Furthermore, the patent introduces an NPN-HBT (Hetero-junction Bipolar Transistor), which consists of a collector diffusion layer formed simultaneously with the N layer of the variable capacitor, a collector layer, and a Si/SiGe layer grown simultaneously with the P layer of the variable capacitor. By ensuring that the depletion layer within the PN junction of the variable capacitor extends entirely across the N layer, Sugiura's invention effectively suppresses the reduction in the variation range of capacitance.
