Abstract

PURPOSE:To effectively prevent the latch-up in a bipolar IC by providing a resistance region between a region becoming an emitter of a parasitic transistor and a power source and always holding the emitter potential of the transistor at a voltage lower than the power potential. CONSTITUTION:In a bipolar IC shown, parasitic transistors Qn, Qp form a parasitic capacitance, causing a latch-up. Accordingly, a p type region 8 connected directly to Vcc is connected via an n<+> diffusion region 15 formed simultaneously upon diffusion of an emitter. That is, an n type resistor Rs 27 is connected in series between the region 8 becoming the emitter of the parasitic transistor Qp 23 and the Vcc, thereby always holding the potential of the region 8 lower than the potential of the Vcc. Thus, even if a latch-up occurs, causing the Qp 23 to become conductive, the voltage is dropped by the Rs 27, thereby eliminating the forward between the emitter and base of the Qp 23. Accordingly, the latch-up is not actually produced.
