Title: Semiconductor device
Inventor: TAKASE NORIYOSHI
IPC: H01L21/3205
Filed: 1987-08-05
Abstract: PURPOSE:To reduce the depth of a contact hole, to decrease an aspect ratio, to uniformize the forming state of a second metal film and to preferably cover a metal film in the hole by forming a first metal film in advance and forming the hole of the insulating film thereon. CONSTITUTION:After an insulating film 6 is formed on a semiconductor substrate 1 including a polycrystalline silicon film 5 and a metal film 9 formed thereon, its part is removed to open a contact hole 7 to expose the films 5, 9, and a metal film 8 is patterned on the opening and the film 6. The film 8 is wired through the hole 7, and wirings through the film 9 in the hole 7 and not through the film 9 are provided. Since the former is already formed with the film 9, the hole 7 becomes shallower as compared with the case having no film 9, and since the latter is already formed with the film 5 on the film 2, the hole 7 becomes shallow. Thus, both have small aspect ratio of the hole 7 and small irregularity to improve the covering characteristic of the wiring metal film in the hole.

Inventor: TAKENAKA MASAHIRO
IPC: H02P5/68
Filed: 1988-08-08
Abstract: PURPOSE:To eliminate wasteful consumption of batteries by combining a motor and batteries so that the motor can be driven at a high efficiency. CONSTITUTION:In a computing element 5 a rotating speed against motor load characteristic and a field current against armature voltage as well as a rotating speed characteristic are set as a data. When a motor is driven with a battery B1, if it is judged that the efficiency of a motor M1 becomes maximum, then switches S1 and S4 only are turned ON by a speed setter 2. If the loss of the motor M1 exceeds the loss when the motor is driven at the voltage of the battery B1 + the battery B2, with a switch S3 ON and by connecting the batteries B1 and B2 in series the motor M1 is driven. In this way, by switchingly connecting the batteries B1 and B2 and motors M1 and M2 to be highly efficiently, the battery consumption is saved.
