Patent JP-H10284835-A (JP)
Title: Manufacture of printed wiring board
Inventor: NIKI NORIO
IPC: H05K3/46
Filed: 1997-04-01
Abstract: PROBLEM TO BE SOLVED: To prevent the positional deviations of a mask pattern and a resist pattern by forming a photosensitive resin layer on a substrate carrying a formed conductor circuit and providing an opening for forming a via hole by exposing and developing the resin layer through a glass substrate carrying a plotted mask pattern, and then, forming the conductor circuit and via hole on and into the resin layer. SOLUTION: An opening for forming a via hole is provided by exposing and developing a photosensitive layer 6 which becomes an interlayer resin insulating layer through a glass substrate 13. Since the used photomask is made of glass having a small, coefficient of linear expansion, the size of the photomask hardly changes even when the humidity and temperature change. Therefore, the mask pattern and a resist pattern hardly cause positional deviations and, accordingly, the positions of a via hole, the solder pattern, and a solder resist pattern are hardly deviated.

Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of a semiconductor device for forming a nitride film used for the dielectric film of a capacitor and the tunnel insulating film of a transistor and to provide a semiconductor manufacture apparatus for forming the nitride film. SOLUTION: Nitrogen which is chemically active is generated by adequately heating nitrogen, with which a process chamber 10 is filled at a high temperature (for example, not less than 1,400 deg.C). A wafer 30 is inserted quickly into the process chamber 10 filled with activated nitrogen, and the wafer 30 is nitrided. Even if wafer temperature is in the middle of rising, a nitriding reaction is started by nitrogen which is chemically active. Desired inside-film nitrogen density is obtained before the wafer temperature reaches a thermally balanced state (1,400 deg.C), and the wafer 30 is pulled out of the process chamber 10 at that time. the increase of thermal jet in an N2 nitriding process can be solved by forming the nitride film through the use of nitrogen which is chemically activated.

Title: Sealed alkaline storage battery
Inventor: SATAKE HISASHI
IPC: H01M10/52
Filed: 1980-06-18
Abstract: PURPOSE:To simplify the process of charging a sealed alkaline storage battery by using an alkaline electrolyte containing a reducing phosphate which doesn't give any negative effect to battery performance, and making the charge capacity of the negative electrode sufficiently larger than that of the positive electrode. CONSTITUTION:A sealed alkaline storage battery is constituted by using an alkaline electrolyte containing a reducing phosphate such as sodium hypophosphite or potassium hypophosphite.
