Title: Photoetching method
Inventor: MATSUZAKI KAZUO
IPC: H01L21/027
Filed: 1984-04-12
Abstract: PURPOSE:To enable dry development by a method wherein the surface is brought into contact with O2 after exposure of positive resist, and photosensitive resist is ashed by irradiation with ultraviolet rays. CONSTITUTION:A positive resist 3 is applied to an SiO2 film 2 on an Si substrate 1 and then exposed to the light 5 of a mercury vapor lamp via photo mask 4. Housed in a reaction chamber 10 with an O2 atmosphere, the substrate 1 is scanned with a beam 6 of ArF laser light 13. Since chains of the molecular structure are cut in the photosensitive part 31, the resist is ashed by the action of activated O2 produced by the light 6 to the O2, and is then removed by dispersion in the form of O2, CO2 or N2. Thereby, a resist pattern 3 corresponding to the light shielding part 41 of the mask 4 is formed on the SiO2 of the substrate 1. When the resist 3 is exfoliated after etching, the SiO2 pattern comes to remain. This construction unnecessitates the post-baking of resist and reduces the possibility of contamination because of no use of liquid.

Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To enhance oxygen overvoltage by adding a cadmium compound into a positive electrode active material and to increase the capacity of a nickel positive electrode plate by restricting the amount of its addition to a minimum. SOLUTION: This manufacturing method includes an active material packing process whereby a positive electrode active material composed chiefly of nickel hydroxide is packed into a sintered base and a current-conducting process whereby the sintered base with the positive electrode active material packed therein by the active material packing process is made to conduct a current in an aqueous solution containing cadmium nitrate as its main component. A compound composed chiefly of cadmium hydroxide is electrolytically deposited on the surface of the positive electrode active material by the current conducting process. Therefore, the compound composed chiefly of the cadmium hydroxide can be deposited mainly on the highly conductive part of the plate packed with the positive electrode active material.
