Title: System for adjusting pattern forming film of printed wiring board
Inventor: YAGASAKI AKIRA
IPC: H05K3/00
Filed: 1999-09-14
Abstract: PROBLEM TO BE SOLVED: To reduce the adjusting error of a film for forming build-up layer pattern by adjusting the target mark of the film for forming build-up layer pattern and a pattern adjusting mark. SOLUTION: The copper foil of copper foil with resin in a build-up layer is partially hollowed and removed so that a pattern adjusting mark 2 in a lower layer can be read through the build-up layer (3 in (1)). The pattern marks 2 at four corners are read by a camera, the expansion/contraction of a base material is calculated from the mutual position relation and the corrected film for forming build-up layer pattern is outputted by reflecting a calculation result. The corrected film is overlapped with a work board to which dry film for etching resist is sealed. The positions of a film target mark and the pattern adjusting mark 2 on the film are positioned and they are exposed and etched. Thus, the pattern of the build-up layer is formed (2).

Title: Manufacture of conductivity modulation type mosfet
Inventor: KUMAGAI NAOKI
IPC: H01L21/336
Filed: 1988-10-15
Abstract: PURPOSE:To improve latch-up resistance, restrain irregularity, and improve yield by leaving a plurality of island type poly Si parts along the end edge of an aperture formed by an aperture forming process, as a mask at the time of forming an emitter.source shorting region. CONSTITUTION:A plurality of island type poly Si parts 20a along the edge of an aperture 21 formed by a forming process of the aperture 21 are left, and used as a mask to limit an edge when an emitter.source shorting region 40 is formed. As a result, the edge of a P-base region 27 is determined by the edge of a poly Si layer 20 of the aperture 21, and the edge of the emitter.source shorting region 40 is determined by the edge of the island type poly Si part 20a. Since the edges are determined by the same mask, the influence of mask shift is avoided, self-alignment process is realized, and the edge of the emitter.source shorting region 40 can be diffused and formed as far as the vicinity of a channel. Thereby, latch-up resistance is improved, irregularity is restrained, and yield is improved.

Title: Forming method of bump in semiconductor device
Inventor: KUBO KAZUYA
IPC: H01L31/10
Filed: 1986-10-30
Abstract: PURPOSE:To form a bump easily with excellent reproducibility and uniformity by removing a second photo-resist as an upper layer, then removing surface layer of a first photo-resist as a lower layer by a releasant and taking off the first photo-resist through exposure and development to shape an overhang. CONSTITUTION:A bump region is removed by a second light-shielding photo- mask 5-1 in a second photo-resist in an upper layer, i.e. a negative type photo- resist 3, and a first photo-resist in a lower layer, i.e. a positive type photo-resist 2, is exposed by using a first light-transmitting photo-mask 5-2. The light- transmitting photo-mask 5-2 is shaped in size larger than the photo-mask 5-1, and the negative type photo-resist 3 is overhung when the positive type photo- resist 2 is removed. Accordingly, a bump having excellent reproducibility and uniformity is formed through a simple process in which the surface of the lower- layer photo-resist 2 is taken off by a release liquid and the photo-resist 2 is removed through development, thus mass-producing a hybrid type infrared image sensor with high yield.

Satisfactory fixability peculiar to polyester resin is due to a molecular skeleton represented by -CO-O- CH2 CH2 -O- in the skeleton of the principal chain of each molecule. In order to reduce demerits while making use of the characteristic, elasticity due to an aliphatic double bond and rigidity due to a phenyl group are imparted by disposing -HC=CH- and a phenyl group near -CO-O-CH2 CH2 -O-.

Abstract: PURPOSE: To prevent a travel from being disabled by measuring the battery voltage of the unmanned traveling vehicle when the unmanned traveling vehicle reaches a reference station, and moving the unmanned traveling vehicle to an electric charging station in a guide path when the battery voltage is lower than a reference value. CONSTITUTION: In addition to work stations, a home base (reference station) and the battery charging station are provided in the travel path of unmanned vehicles, and the ground-side communication controller at the home base sends a precedence signal to the communication device 44 on an unmanned traveling vehicle.
