摘要:
A flat-pack type semiconductor device has an anode buffer plate (50) on a semiconductor element (1). The anode buffer plate consists of a central position (51) and a plurality of arms (61, 63) extending therefrom. Each of the arms has a straight portion (61a) placed on a guide ring (70) and a hooked-portion (61b) inserted in the gap (73) between the guide ring and an insulating cylinder (10).
