Title: Semiconductor device
Inventor: OKIDO TOSHIO
IPC: H01L27/04
Filed: 1989-01-19
Abstract: PURPOSE:To obtain a MOS capacitor whose dielectric breakdown strength against static electricity is made high without making the insulating film between a metallic electrode and a diffused electrode thick, by a method wherein two high-concentration N-type impurity diffused regions, whose depths are different from each other, are provided in an N-type epitaxial region of a P-type substrate. CONSTITUTION:A MOS capacitor has a high-concentration N-type impurity buried region 6 and a high-concentration N-type impurity diffused region 4, which comes into contact with this buried region 6 and has a deep diffusion depth, in addition to a high-concentration N-type impurity diffused region 3 which is used as a diffused electrode. That is, the region 3 is connected to the region 6 through an N-type epitaxial region 5 and is connected to a metal film 1 through the region 4. In such a way, by preventing a charge concentration between the diffused electrode and a metallic electrode in the MOS capacitor, the dielectric breakdown strength of an insulating film against static electricity can be made high without increasing the film thickness of the insulating film between the diffused and metallic electrodes.

Title: Current feedback type push-pull converter circuit
Inventor: DOI YOSHIAKI
IPC: H03H7/09
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To improve the power factor of an AC input voltage by connecting a large-capacity flyback voltage storing capacitor to the auxiliary winding of a current feedback inductor and the connecting point to the input side and main winding through a reverse-current preventing diode. SOLUTION: When an AC voltage from an AC input power source 1 is supplied to the center tap of a transformer 10 through a current feedback inductor 7 after the voltage is rectified and smoothed and operates a push-pull inverter, a flyback phenomenon occurs. Then an electric current flows to a large-capacity flyback voltage storing capacitor 6 for reducing ripple from a flyback diode 8 through the auxiliary winding of the inductor 7 and, further, toward the power source 1 through a reverse-current preventing diode 5 so as to discharge the energy stored in the main winding of the inductor 7. The capacitor 6 is charged with this current only and the charging/discharging currents of the capacitor 6 do not work as a capacitor input type without receiving any direct influence from an AC input current from the power source 1. Consequently, the power factor of the AC input power is improved.
