IPC: H02M3/28
Filed: 1980-02-12
Abstract: PURPOSE:To reduce a switching loss at high switching frequency by forming the circuit with provision of damper diodes and resonant capacitors at both ends of respective switching elements connected in series. CONSTITUTION:The series circuit of two switching elements 3 and 4 is connected in parallel to DC power sources 1 and 2 connected in series and further the damper diodes 11 and 12 and the resonant capacitors 13 and 14 are connected in parallel to each of switching elements 3 and 4. And, through the intermediary of the power- transmitting transformer 5, to the secondary winding thereof are connected rectifying circuits 7 and 8, a choke coil 6 and a capacitor 9, whereby an output is obtained. Accordingly, the sharp change in the both-end voltage of the switching elements 3 and 4 is controlled by the capcitors 13 and 14, thereby overlapping of current can be reduced, and thus the switching loss can be kept at a very low level even when the frequency becomes high.

Title: Formation of thin film
Inventor: MATSUI SHINJI
IPC: H01L21/318
Filed: 1988-01-25
Abstract: PURPOSE:To simplify a thin film forming process, by implanting nitrogen ions in a silicon substrate for selectively forming a silicon nitride layer, and performing selective epitaxy. CONSTITUTION:Nitrogen ions are implanted in a silicon substrate 11 by means of nitrogen ion beams 13, so as to form a nitrogen ion implanted region 13. Then, a mask 12 is removed. In this manner, a silicon nitride layer is formed selectively by implantation of nitrogen ions. Then, an Si epitaxial thin film is formed selectively by means of the gas reaction vapor growth using dichlorosilane such that silicon is not deposited on the nitrogen ion implanted region 13. The ion implantation may be carried out with a low energy since the selective epitaxy utilizes difference in surface energy. In this manner, the thin film forming process can be simplified.
