Abstract

PURPOSE:To enable a device to realize a high speed operation and to obtain a high integration, by a method wherein a Schottky barrier diode is used as a clamp diode for a transistor base and a collector, and a base contacting the periphery of the diode forms a guard ring. CONSTITUTION:A P type region 102 is selectively mounted on a n type semiconductor substrate 101, and a Schottky barrier diode SBD, having a junction surface 105 ranging from the bottom of the region 102 to the inside of a region 101, is formed. A P-N junction, consistig of the region 101 and 102, is formed at a periphery 106 of the SBD, and thereby a reverse direction leak current at the periphery of the SBD decreases, resulting in improving the reverse direction property of the SBD.
