Abstract

PURPOSE:To prevent the overvoltage damage of a semiconductor device due to the vibration voltage during a reverse recovery period by setting the specific resistance of a P type Si substrate of a diode having a P<+> P-N junction formed with a P type Si substrate to a value higher than the specific value. CONSTITUTION:A diode Si plate 100 having an P<+> P-N junction formed with a P type Si substrate is joined integrally in a direction for correcting the reverse blocking capaity of a thyristor Si plate 200 having a P-N<+>N-P-N junction. An anode electrode 4 is formed integrally with the surface of the Si plate 100, and a cathode electrode 5 and a gate electrode 15 are formed integrally with the surface of the plate 200. In the thyristor of this structure, the specific resistance of a central P type layer 2 of the plate 100 is set to a value higher than 1kOMEGAcm. In this manner, the thyristor can be prevented from causing the overvoltage damage due to the vibration voltage during the reverse recovery period, thereby enabling the increase in the withstand voltage of the thyristor.
