Title: Production of semiconductor device
Inventor: WAKEBE HIROSHI
IPC: H01L21/764
Filed: 1979-07-12
Abstract: PURPOSE:To prevent the disconnection and the like of Al wire by forming an isolation region flat on the surface through oxidization with an acid resistant film formed on the opening provided on a region to be oxidized selectively. CONSTITUTION:An epitaxial layer 12 is formed on a p-type substrate 11 having an n-type buried layer 13. A thermal oxide film 14 is provided on the layer 12 and a nitride film thereon. After an opening is formed by etching, the nitride film 17 is formed entirely thereover. Then, plasma gas is admitted at right angle to the substrate 11 to remove the nitride film on the bottom of the opening by plasma etching and oxidization is performed in the atmosphere of wet O2 to form an isolation region 2mum thick, for instance. The nitride film on the side works to introduce the oxidation from the bottom to prevent the formation of the bird head, making the surface of the region flat. This enables finer pattern width of the oxidation on the surface. Thus, higher density of the equipment is possible while disconnection and the like of the Al wire can be eliminated.

Filed: 1988-04-13
Abstract: PURPOSE:To easily realize low-loss optical coupling between an optical waveguide and optical fibers by finishing at least part of the waveguide-side end faces of the optical fibers to have oblique faces. CONSTITUTION:V-grooves 6-8 are formed on a crystal base plate 1, on which an optical circuit constituted of optical waveguides 3-5 is formed by a crystal anisotropic etching process and optical fibers 9, 11, 13 respectively provided with obliquely finished faces at, at least, part of the waveguide-side end faces are optically coupled with the waveguides 3-5 by closely putting the fibers 9, 11, and 13 in the grooves 6-8. Since the V-grooves 6-8 are formed monolithically on the base plate 1, necessity of complicated optical axis adjustment is eliminated and, moreover, since the crystal anisotropic etching process applied to the grooves 6-8 can be carried out collectively on the plural grooves with an inexpensive device, the productivity and economical efficiency of this optical coupler are improved. In addition, since the end faces of the optical fibers 9, 11, and 13 are finished to have the oblique faces, the end faces of the optical fibers 9, 11, and 13 can be brought nearer to the optical waveguide to prescribed intervals. Thus low-loss optical coupling can be realized between the waveguides 3-5 and fibers 9, 11, and 13.

IPC: B23K13/00
Filed: 1984-05-01
Abstract: PURPOSE:To execute welding in the stabilized state of a weld point by generating a magnetic flux so as to negate the electromagnetic force of the magnetic flux generated by welding current from both upper and lower induction coils of a weld zone to said magnetic flux. CONSTITUTION:The welding current i0 is supplied from one contact chip 2 toward a V-converging point 1b through a route 4.

The induction coils 3 are provided above and below the point 1b so that the current (i) in the direction opposite from the direction of the welding current i0 flows. The magnetic flux phi to be generated from the coils 3 is made opposite in the direction from the magnetic flux phi0 to be generated from the current i0. The magnetic flux phi0 generated by the current i0 is therefore offset by the magnetic flux phi and the welding is executed without application of electromagnetic force to the edge end faces and without fluctuating the weld point.

Filed: 1984-05-07
Abstract: PURPOSE:To have sure semi-clutching operation by driving a clutch actuator with a constant force, and by sensing semi-clutch condition by means of study from change in the moving speed of an actuator rod. CONSTITUTION:As this clutch actuator 3 is given a constant driving force by a drive control means 7, the moving speed of the operating rod of actuator differs depending upon the state: i.e. while the clutch 2 is disengaged, in semi-clutching or in engagement. Thus the moving speed of the actuator rod is sensed by sequentially differentiating the output of a sensing means 6, and the semi-clutch operating zone is sensed through utilization of the change in this speed. Accordingly the semi-clutch operating zone can be sensed even when the drive motive 1 is off rotation. This enables sure semi-clutch operation.
