Claims

[Scope of utility model registration request]

In a semiconductor device in which a cathode emitter region and a gate region are formed in a single portion of a semiconductor pellet, a plurality of cathode emitter groups formed in an island shape are arranged radially from the center of the pellet, and the emitter groups are arranged in a radial pattern. The cathode emitters are separated and arranged in parallel in the circumferential direction so that one end faces toward the center, and the center part of the cathode emitter group is the longest, and the cathode emitters arranged at both ends in the circumferential direction are the shortest, A semiconductor device characterized in that an angle formed by a tangent line connecting one end of each cathode emitter toward the center between adjacent cathode emitter groups widens toward the center.
