Title: Formation of micropattern
Inventor: OGURA KEN
IPC: G03F7/36
Filed: 1981-06-23
Abstract: PURPOSE:To facilitate dry patterning of a resist film, by using a photosensitive resist consisting of a mixture of a photosensitive resin and a silylating or acylating agent. CONSTITUTION:A photosensitive resist layer 13 composed of a radiation-sensitive resin, such as polyacrylate, and a silylating or acylating agent is formed on the heat-oxidized film of silicon 12 provided on a semiconductor substrate 11. The resist film 13 is irradiated with electron beams 14 in accordance with a prescribed pattern. The substrate 11 is set in an etching tunnel 16, and exposed to oxygen plasma to remove the parts of the film 13 not exposed to the electron beams 14, thus permitting a resist film pattern 13a to be formed. The unnecessary parts of the film 12 are removed by ion etching using the pattern 13a as a protective film, and further, the pattern 13a is removed, thus permitting the film 12 to be patterned.

Title: Manufacture of crystalline semiconductor thin film
Inventor: YAZAKI MASATOSHI
IPC: G02F1/136
Filed: 1990-04-11
Abstract: PURPOSE:To obtain crystalline semiconductor of high quality having less deterioration and contamination, a flat surface and large hydrogen content by holding crystallized semiconductor thin film between two layers of silicon nitride films, and emitting it with a laser beam. CONSTITUTION:A silicon nitride film 2, an amorphous silicon film 3 and a silicon nitride film 4 are sequentially laminated on an insulating base 1. That is, since the film 3 is formed in a structure in which it is interposed to be held between the films 2 and 4, the film 3 is not exposed with the atmosphere to reduce its contamination and deterioration. Then, the film 3 is converted into a polycrystalline silicon film 9 by emitting it with a laser beam 5. Thus, hydrogen contained in the films 2, 4 is diffused in the molten silicon film to fill a defect in the film 9 to provide the film of high quality. Therefore, the film 4 prevents the hydrogen from being separated into the film 9, suppresses the uneven part of the film 9 to be generated in the case of solidifying it to obtain a flat film.
