Title: Manufacture of semiconductor device
Inventor: HIRATA TADASHI
IPC: H01L21/768
Filed: 1994-12-28
Abstract: PURPOSE: To reduce a difference in level formed between a part wherein a wiring pattern is formed and a part wherein this pattern is not formed, by applying electrons onto the surface of a plasma TEOS film after the plasma TEOS film is formed and before an ammonia plasma treatment is applied onto the surface of this film. CONSTITUTION: After a wiring layer is deposited on the whole surface of a wafer 10 and a wiring pattern 12 is formed by etching, a plasma TEOS film 14 is formed by a plasma CVD method and electrons are applied. On the occasion when an ozone TEOS film 18 is formed by applying an ammonia plasma treatment onto the whole surface of the plasma TEOS film 14, the ozone TEOS film 18 is formed to be thin on the wiring pattern 12 and to be thick in a part except this pattern by the application of electrons. Accordingly, a difference in level between a part wherein the wiring pattern 12 is formed and a part wherein this pattern is not formed can be reduced and, therefore, reliability of the wiring pattern formed on a layer insulating film can be improved.

Abstract: PURPOSE:To eliminate the irregular disposition of a magnetic deformation as seen from a rotor and to obviate a magnetic vibration by spirally welding axially to the outer periphery of a stator core formed by laminating steel plates. CONSTITUTION:Annularly punched steel plates are laminated to form a stator core 1. The bore face 2 of the core is formed to be circular, a rotor is inserted thereto, and a predetermined number of slots 3 are simultaneously punched on the bore face 2. A spirally welded part 4 is formed by axially welding the core 1 while rotating the laminated core 1. Thus, the magnetically irregular disposition of the stator as seen from the rotor is eliminated thereby to compose a motor having less magnetic vibrations.

IPC: H01J9/227
Filed: 1987-12-25
Abstract: PURPOSE:To prevent a black matrix formed on a panel surface from generation of defoliation by treating a photo-absorbing film formed over the whole panel with an aque. solution of multi-value salt prior to the defoliating liquid treatment process. CONSTITUTION:A film of photo-sensitive substance is formed on the inner surface of a panel of cathode-ray tube, and exposure is made to harden the photo- sensitive substance in the exposed portion, followed by removal of unexposed portion and development, and a pattern consisting of the photo-sensitive substance is formed. A film is formed on this developed surface from a photo- absorbing substance, and as multi-value salt an aque. solution of calcium nitrate is injected into the photo-absorbing film, and then a defoliating liquid is injected to defoliate and remove the photo-sensitive substance. Consequently the diffusing agent added to the photo-absorbing substance is made insoluble and remains within the photo-absorbing material even in the development treating process, so that the film of photo-absorbing substance is strengthened and the bonding force with panel increased. Thereby the black matrix formed on the panel surface is free from risk of generation of irregular defoliations.

Title: Packaging design device and method therefor
Inventor: MIURA SHINJI
IPC: H05K13/00
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To prevent important connection lines on a substrate from being formed as zigzag lines or complicated lines as much as possible by specifying the connection lines on a circuit diagram, forming wiring routes on a board, determining the mounting positions of parts in the vicinity of the wiring routes, and determining a wiring route between pins attached to the parts and a wiring route between a wiring reference pattern and each part. SOLUTION: The mounting positions of wiring reference patterns 1 to 3 are determined from the important connection lines on the board for a power supply/ground line or the like. These patterns 1 to 3 have shapes based on the vertical and horizontal dimensions of a wiring foil and the frame of the wiring routes can be previously determined before the positioning of parts. Since the patterns 1 to 3 are provided with connection pins, the mounting positions of the patterns 1 to 3 can be determined similarly to parts. When the mounting positions of packaging parts R1 to R4, TR1 to TR3 are determined after determining the mounting positions of the patterns 1 to 3, connection lines can be straight formed and the packaging parts R1 to R4, TR1 to TR3 are arranged around the connection lines to generate a substrate layout.  Consequently the electric characteristics of the connection lines to be applied to the board can extremely be improved.

Abstract: PURPOSE:To improve the yield on the manufacture by differentiating an impurity concentration of a 2nd conduction semiconductor layer from a direction perpendicular to a propagation direction of a surface wave so as to widen an excellent bias width of a convolution efficiency FT. CONSTITUTION:A 2nd conduction semiconductor layer consists of two regions comprising a 1st 2nd-conduction semiconductor layer 14 and a 2nd 2nd- conduction semiconductor layer 15 and the impurity density distribution and its layer thickness of each region are formed differently. However, the semiconductor layers 14 15 form one border face at the lower part of a gate electrode 8, the boundary surface is in parallel with a propagation direction of a surface wave to divide the region beneath the electrode 8 into nearly two. Thus, the 2nd conduction semiconductor layer beneath the electrode 8 is almost divided into two by the two regions whose impurity density distribution and layer thickness differ. Thus, since the bias width with an excellent convolution efficiency is spread, the yield on the manufacture is improved and the manufacture cost is reduced.
