Title: Semiconductor device and power converter
Inventor: MIZOGUCHI TETSURO
IPC: H01L29/74
Filed: 1994-06-30
Abstract: PURPOSE:To realize a high power device having the low loss characteristics of an Si thyristor and the high breakdown strength and normal-off characteristics of a GTO. CONSTITUTION:A p-layer 11 having the total amount of impurities from 10<12>cm<-2> to 10<14>cm<-2> us formed so as to cover a p-type gate layer 10. When the total amount of impurities reaches 10<12>cm<-2> or more, normal-off characteristics are obtained. Since breakdown strength determined by avalanche breakdown does not depend upon the bias state of a gate approximately, high anode breakdown strength is maintained even at the time of the abnormal operation of a gate circuit. Approximately the same breakdown strength characteristics as a GTO are acquired by above-mentioned structure. When the total amount of impurities per the unit area of a region 20 penetrated to the P-layer 11 reaches 10<14>cm<-2> or less while breakdown strength is kept under the conditions, the quantity of electrons infected from a cathode can be increased, thus largely reducing loss.

IPC: H01L41/09
Filed: 1982-08-27
Abstract: PURPOSE:To contrive reduction in the amount of displacement under the state of DC driving by a method wherein a ferrodielectric piezo-electromagnetic plate, which is electropolarized in the same direction as the applied electric field, and an ion-crystalline plate having transversal oscillation effect for applied electric field are laminated thereon. CONSTITUTION:A parallel piezoelectric bimorph is constituted by directly laminating an ion-crystalline plate 12 and an electropolarized ferroelectric piezo-electromagnetic plate 11, and an ion-crystalline plate 12 and a ferroelectric piezo- electromagnetic plate 11 are laminated on both sides of said conductive metal plate through the intermediary of a series type or thin conductive metal plate. When a voltage is applied as shown in the diagram, the ion-crystalline plate 12 expands and the piezoelectric electromagntic plate 11 contracts, thereby transforming them into curved form as shown by the chain lines in the diagragm. Thus, the ion-crystalline plate 12 expands as a result of the displacement of an ion, it does not expand due to electropolarization, and there is no attenuation in electropolarization. Accordingly, the reduction in the amount of displacement can be contrived even in the electric field for a long period or the electric field is repeatedly applied.
