Title: Semiconductor device and its manufacture and structure for mounting
Inventor: TANAKA SHINICHI
IPC: H05K3/32
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To reduce as much as possible planar size and depth of dimples on the surface of conductor bumps, to increase the number of conductive particles contributing to conduction of the conductive bumps, and to improve the reliability of implementation of a semiconductor device. SOLUTION: A semiconductor device is GCOG (chip-on-glass) mounted on a liquid crystal glass panel to be used for a liquid crystal display device. A semiconductor chip 1, whose main surface is convered with an insulating layer 3, is provided with a conductive bump 4 which is formed by growing a metal on an electrode pad 2. The conductive bump 4 is electrically connected to the electrode pad 2 via an operating 3a of the insulating layer formed on the electrode pad. The area of the opening 3a is 1/9 or less of an area opposite an electrode 8 of the bump. A dimple 4a is produced on the top of the conductive bump because of different levels of the insulating layer 3. The size of the dimple 4a is at least 1/9 or less of the conductive bump, and its depth is also reduced in comparison with a conventional structure.

Title: Oxygen sensor for internal combustion engine
Inventor: UCHIKAWA AKIRA
IPC: G01N27/407
Filed: 1986-09-01
Abstract: PURPOSE:To prevent the delamination of a protective layer, in an oxygen sensor wherein electrodes are provided to the inner and outer surfaces of a zirconia tube, by providing the first catalyst layer and the protective layer to the outer surface of said tube and providing the second catalyst layer on said protective layer. CONSTITUTION:Platinum is applied to the outer surface of the leading end part of a zirconia tube 2 by vapor deposition to form the first catalyst layer 20 which is, in turn, covered with a protective layer 21 composed of oxide of a magnesium spinnel. Platinum is applied to the end part of the protective layer 21 by vapor deposition to form a second catalyst layer 22. Further, a protector 3 is provided outside the zirconia tube 2 to open a slit 3a and exhaust gas is introduced from the slit 3a. At this time, the atmosphere of the first catalyst layer 20 generates no precipitation of carbon because of the good replacement of exhaust gas. However, the exhaust gas stagnates at the base end part of the zirconia tube 2 and hydrocarbon is precipitated as carbon by the second catalyst layer 22. Since said carbon is formed on the outer surface of the protective layer 21, the protective layer 21 is not released. Since the second catalyst layer is provided, the delamination of the protective layer 2q can be prevented.

Title: Method for recognizing object
Inventor: YOSHIDA YUTAKA
IPC: G06T1/00
Filed: 1985-09-18
Abstract: PURPOSE:To improve the recognizing accuracy of an object by giving a finer sampling rate to a remote spot than a near spot within a camera viewfield. CONSTITUTION:Picture signals picked up by a camera 4 are supplied to a picture memory 9a via a switch circuit 8. An arithmetic processor 10 reads out the contents of the memory 9a and those of a picture memory 9b storing data on a reference state and compares both contents with each other to check whether a luminance value has a change or not. If the luminance value has some changes, the similar comparison is given also to the peripheral picture elements. Then the processor 10 presets data so that a clock pulse is changed for each horizontal synchronizing signal. Therefore, the video signal undergoes sampling with different clock pulses for each scan. Thus the equal weighting is secured between picture elements of the object at the remote and near spots.
