Abstract
PURPOSE: To prevent braze material from creeping up to side face of pellet by so forming mesa grooves that they reach the semiconductor substrate of an SCR pellet from the main face on the opposite from the semiconductor substrate.
CONSTITUTION: A PB layer 3a and NB layer 2 are superposed on an N+ type substrate 4a and a P layer 1 is provided on the layer 2. From the main face on the P layer 1 side, mesa grooves are made and an insulation film 9 is made on the side wall face, thence electrodes 7, 8 are provided. According to this constitution, the side face is only the N layer 4a and there are no influences at all on the various characteristics such as reverse dielectric strength, etc. even if the braze material creeps up on the side face at the time of brazing the electrode 8 to the metal frame. Hence, the bonding conditions may be eased and the semiconductor substrate may be made thick, thus resulting in reduced cracking.
