Latest Patents

Fujii's latest patents include a method of manufacturing a semiconductor device that comprises a bipolar transistor and a variable capacitor. This innovative variable capacitor features an N layer that includes a variable capacitance region, a P layer that is epitaxially grown on the N layer and formed from a SiGe film and a Si film, and a P-type electrode. Additionally, his NPN-HBT (Hetero-junction Bipolar Transistor) includes a collector diffusion layer that is formed simultaneously with the N layer of the variable capacitor, a collector layer, and a Si/SiGe layer that is epitaxially grown simultaneously with the P layer of the variable capacitor. This design allows the depletion layer formed in the PN junction of the variable capacitor to extend entirely across the N layer, effectively suppressing the reduction in the variation range of the capacitance.
