摘要: A semiconductor device with a bipolar transistor and a capacitor that has a down-sized circuit area is presented. During the manufacture of the bipolar transistor, a polysilicon-insulator-polysilicon capacitor, a polysilicon-insulator-metal layer or a metal-insulator-metal capacitor can be formed on the isolating insulator and/or the protective insulator to achieve reduced circuit area, less manufacturing steps and lowered manufacturing cost.
