Abstract

PURPOSE: To increase stability against the tray effect, by providing in a common substrate a pair of pnpn switches, each consisting of an anode and cathode equivalently connected in anti-parallel, and providing a difference in the efficiency between the transistors constituting the switches.
CONSTITUTION: By diffusion, four p-type regions 24, 24', 25 and 25' are formed in common n-type region 23, which is supported by substrate 21 and separated from other circuit elements by dielectric film 22. Next, n+-type regions 26 and 26' are formed in regions 25 and 25'. In this way, region 23 is made common, regions 24 and 24' are made into an anode, regions 25 and 25' are made into a gate, and regions 26 and 26' are made into a cathode, and thereby a pair of pnpn switches are obtained. By connecting regions 24 and 26', and 24' and 26, a pair of anti- parallel-connected pnpn switches are formed, and a difference in current amplification factors between a pair of horizontal transistors constituting the switches is provided.
