摘要： PROBLEM TO BE SOLVED: To uniformly electrically press-contact a gate post element, in the outer peripheral gate structure or intermediate gate structure of a large-capacity element with a metallic current collecting gate electrodes. SOLUTION: In a semiconductor device, having a semiconductor element in which metallic current collecting gate electrodes are formed on the surfaces of a plurality of slit-like N-type cathode regions and an annular gate post electrode 21 which is electrically connected to the external gate terminal, in such a way that the electrode is press-contacted with the metallic current collecting gate electrodes, many small projections A are provided on the surface of the gate post electrode 21, which is press-contacted with the metallic current collecting gate electrodes. When a press-contact force is applied to the electrode 21, the electrode 21 is press-contacted with the gate electrodes, in such a way that the projections A bite into the gate electrodes. Since all of the minute projections A are press-contacted with the gate electrodes, even when the press- contacting force is not uniform as long as the variation of the force falls within the thickness varying range of the projections A, no concentration of current will occur.

摘要： PROBLEM TO BE SOLVED: To obtain a distributed power supply, wherein it is unnecessary to increase the capacitance of a semiconductor device, even if overcurrent is allowed for, by limiting the current passed through the system linkage switch when an overcurrent is passed through a first system linkage switch. SOLUTION: If an overcurrent is passed through a system linkage switch 3, a linkage switch current detector 14 detects the overcurrent, and an overcurrent detection signal from it is input to a second linkage switch control circuit 16. The linkage switch control circuit 16 issues a striking command to the thyristor of a system linkage switch 15. Since the on-voltage of the thyristor is lower than that of IGBT, most of the current is passed through the system linkage switch 15 by turning on the system linkage switch 15. This brings the first system linkage switch 3 out of the overcurrent state and makes it unnecessary to increase the capacitance of a semiconductor device, comprising the first system linkage switch 3.

摘要： PROBLEM TO BE SOLVED: To repair a failure cathode area and provide a large capacity element. SOLUTION: Among a plurality of N type cathode areas, a cathode metal electrode 11 on a failure cathode area 3A is removed, then, a P type layer 20 is formed so as to bury between the P type gate layers 4 adjacent to the failure cathode area 3A. The P type layer 20 actually insulates the failure cathode area 3A from an N type base layer 7, and since only this part is allowed to have a structure same as that of GTO(gate turn-off thyristor), the berakdown strength between the gate and the cathode recovers.
