Title: Semiconductor device and electrode block therefor
Inventor: SATO KATSUMI
IPC: H01L23/48
Filed: 1989-12-15
Abstract: PURPOSE:To stabilize the control characteristics of a semiconductor element by a method wherein the second surface of a first external main electrode has a first area facing the protruding part of the first surface and a second area facing a part of the recessed part of the first surface and the height of the second area is smaller than the height of the first area. CONSTITUTION:A first area 33a faces a protruding part 31 and a second area 33b faces a trench part 35. Further, a third area 33c faces a wall 34 and a lower surface part 36 extending from the wall 34. If a large pressure is applied through members 51 and 52, the circumference part of the member 51 itself is deformed but the deformation is not transmitted to the trench part 35. Thus, as an unnecessary external force is not applied to the recessed part 35 facing the control conductor part in an external main electrode, the deformation of the recessed part 35 is avoided and a force applied to the control conductor by an elastic member contained in the recessed part 35 is not varied by an external force, so that the instability of the control characteristics caused by the deformation of the external main electrode can be avoided.
