Abstract: PURPOSE:To contrive prevention of the breaking of wire at the edge part of the titled semiconductor device by a method wherein a contact hole, the upper part of which has a large diameter, is formed utilyzing the difference of etching speed generated by the difference in the condition of heat treatment to be performed on a film, thereby enabling to smooth the edge part of the contact hole. CONSTITUTION:On a PSG film 13, a PSG film 14 is deposited in the thickness of 2,000- 4,000Angstrom  as an insulating film of the same composition as the film 23, and a heat treatment of the lower temperature and the shorter time than the heat treatment of the PSG film 13, wherein almost no diffusion of diffusion layer impurities will be generated, is performed. Then, photoresist 15 is applied to the PSG film 14, an aperture part 16 is formed, and when an anisotropic etching is performed on the prescribed part of the PSG films 13 and 14, a contact hole 17 is formed almost in vertical direction. Subsequently, when an isotropic etching is performed the upper layer PSG film 14 is etched in lateral direction larger than the lower layer PSG film 13 due to the difference of etching speed caused by the difference in heat treatment condition, and the contact hole is formed in an inverted convexity. Subsequently, after the resist 15 has been exfoliated, a heat treatment is performed for the purpose of smoothing the edge part of the contact hole 17.

Title: Wiring tester
Inventor: MIHO TAIICHI
IPC: G01R31/02
Filed: 1985-08-10
Abstract: PURPOSE:To prevent test data from being mixed with redundant data by constituting a wiring tester such that a test terminal originally connected to one test terminal to be uregently tested may not detected as an insulation-defective terminal. CONSTITUTION:When an insulation test is conducted through an all-short test, for example, in a wiring network with a terminal 4' as a remarked terminal, the terminal 4' is selected by a selecting circuit 2 and connected to one terminal of an insulation measuring instrument 4. On the other hand, terminals other than the terminal 4' are selected as mating terminals by a signal transmitter 32 in a selecting circuit 3 and driving signals are fed to corresponding relays in a relay group 31. However, the driving signals for the relays corresponding to terminals 1', 3' and 7' originally connected to the terminal 4' are interrupted (6). In result, terminals except the terminals 4', 1', 3' and 7' are connected as a whole to the other terminal of the measuring instrument 4. In result, in the insulation test through the all-short test with the terminal 4' as the remarked terminal, the terminals 1', 3' and 7' are excluded from the mating terminals an the terminal 7' is prevented from being determined as an insulation-defective terminal.

Title: Production of magnetic recording medium
Inventor: KATO AKIRA
IPC: G11B5/845
Filed: 1986-07-29
Abstract: PURPOSE:To obtain excellent recording/reproducing characteristics by vibrating a magnetic field in a direction parallel with a magnetic coat surface. CONSTITUTION:A magnetic coating material obtained by dispersing magnetic powder uniformly is applied to the surface of a base while rotating the base to obtain a fixed film thickness. Before the magnetic coat film on the base dries out completely, a magnetic disk 1 is constantly rotated at 10-500rpm by a spindle 6. Under said state, magnetic poles 2a, 3a, and 2b, 3b arranged separatedly from the magnetic coat surface of the magnetic disk 1 by 0.5-4mm distance are vibrated in accordance with a time chart shown in a graph. Since the magnetic powder in the magnetic coat film is sharply vibrated at the initial stage, the vibration is converged and its directivity is gradually integrated, the magnetic power can be arranged uniformly in the circumferential direction of the medium base. Thereby, an angular ratio can be improved and a uniform and smooth magnetic coat film can be formed.
