IPC: C23F1/00
Filed: 1990-11-20
Abstract: PURPOSE:To form a multistage substrate, by a method wherein, in a working method of a semiconductor substrate wherein a semiconductor substrate constituted of a P layer and an N layer is dipped in anisotropic etching liquid, and an electric potential is applied to the N layer, an etching protective film is patterned on the P layer surface, an electric potential applied to the N layer is changed, and etching depth is controlled. CONSTITUTION:Firstly, an etching protective film 2a is patterned on the surface of a P layer 1a. A working electrode 4 of a potentiostat 3, a reference electrode 5, and an opposite electrode 6 are connected with an N layer 1b side. Secondly, a substrate is dipped in anisotropic etching liquid such as KOH, NaOH, ammonium hydroxide. Since etching of the P layer progresses for an arbitrary potential of the N layer, the protective film 2a left for forming a step-difference is gradually etched and eliminated in the course of etching. When etching is continued, and the deepest part reaches the vicinity of the N layer, a potential V is fixed to a value higher than or equal to Va capable of stopping etching. By changing the potential in this manner, the step-difference (h) is formed to be a specified value.

Title: Exciting method for contactor
Inventor: WATANABE TOSHIYUKI
IPC: H01H50/42
Filed: 1987-12-14
Abstract: PURPOSE:To prevent the improper attracting operation of a contactor occurring upon a drop in source voltage by positioning a part of a large current circuit wiring near a contactor coil and using a magnetic field generated therein. CONSTITUTION:When a motor current increases due to a large load during running and the source voltage of a battery drops, the exciting voltage of a coil 15a drops with the drop of the source voltage and a magnetic field H1 generated in a coil 15a weakens. On the other hand, a magnetic field H2 generated in a copper bar 18 becomes strong with an increase in motor current. Namely, even when the magnetic field H1 in the coil 15a weakens, the magnetic field H2 in the copper bar 18 works to make a compensation therefor. Due to assistance by the magnetic field H2, therefore, a drop in attraction force of a contactor 15 is prevented.
