Abstract

PURPOSE:To overcome the upper limit of frequency due to the base resistace in a semiconductor device such as, a bipolar transistor by providing a relation of rho>1/2piepsilonf0 between the resistivity rho of the base region and the main operating frequency f0. CONSTITUTION:An N<+> type buried collector 12, an n<+> type collector pickup region 17, an n<-> base and collector high resistance region 13, a p<+> type base pickup region 14, a p type base region 15 and an n<+> type emitter region 16 are respectively formed on a p type substrate 11. The base region 15 is so formed that the resistivity rho of the base region is higher than 1/2piepsilonf0 with respect to the predetermined operating frequency f0.
