Patent JP-S6199332-A (JP)
Title: Plasma etching method
Inventor: SASAKI RIICHI
IPC: H01L21/302
Filed: 1984-10-19
Abstract: PURPOSE:To enable patterning at a constant speed in high accuracy removing a deposit film by carrying out plasma treatment with oxygen gas in plasma etching. CONSTITUTION:A deposit film is formed by plasma etching to a definite film thickness with a carbon fluoride series gas including hydrogen. Then, the deposit film is removed by plasma treatment with oxygen gas. If the plasma etching and the plasma treatment are carried out alternately, the etching can be advanced at a constant speed. Further, since a resist film can be incinerated by oxygen gas plasma and removed, if the changeover of a treatment time is appropriately adjusted, a resist film pattern is also removed at the time of patterning finish and the simplifying of a photo process can also be possible omitting the process of removing the resist film.

When an arrived slot is not 'empty', whether or not the data in the slot are the answer to the data sent last time by the node of its own station is checked and, at the same time, presence of the data transmitted to the node of its own station is checked. When the arrived slot is not 'empty' and the data in the slot are not the answer to the data sent last time from the node of its own station, the slot arrived at the next node is sent as it is.

IPC: C01F7/54
Filed: 1992-08-21
Abstract: PURPOSE:To readily obtain ammonium cryolite suitable as a raw material for producing NF3 by simultaneously adding hexafluoroaluminic acid and ammonia and crystallizing the reaction product in a specific pH range. CONSTITUTION:Hexafluoroaluminic acid and ammonia are simultaneously added, reacted with each other at a reaction temperature of >=30 deg.C and at a reaction pH of 6-8.5, and subsequently subjected to crystallization of the reaction product. The resultant reaction slurry is subjected to solid-liquid separation and then dried to provide the ammonia cryolite having an average particle diameter of 250-350mum and a bulk density of 1-1.2kg/cm<3>. The ammonia may be either gaseous ammonia or liquid ammonia. The hexafluoroaluminic acid as the raw material is obtained by dissolving ammonium hydroxide in hydrofluoric acid in a 6F/Al molar ratio of 0.9-1.1. For the production of NF3, the ammonia cryolite is reacted with elemental fluorine, but NH4AlF4 remains as a reaction residue. When the compound is reacted with 25% ammonia water and with 55% hydrofluorine acid and a pH of approximately 8, the ammonia cryolite is obtained.

A large energy cost is necessitated and is not economical even if the exposing intensity is increased. Duplication without notice is thereby prohibited and the infringement of the portrait right, copyright, etc., is effectively prevented.
