Title: Plasma etching
Inventor: HAMAZAKI RYOJI
IPC: H01L21/3065
Filed: 1988-03-11
Abstract: PURPOSE:To improve anisotropy and mass productivity, and to reduce damage to a work by etching the work by the plasma of a mixed gas consisting of a gas for protecting a sidewall, an etching gas and one of of chlorine, argon, xenon and krypton gases. CONSTITUTION:When a work is etched by C2Br2F4 gas for protecting a sidewall and an etching gas and changed into a vertical shape from a forward tapered shape, an undercut is often generated simultaneously. When the flow ratio of C2Br2F4 to SF6 is fixed under conditions, in which no undercut is generated, and one kind of a gas of Cl2, Ar, Xe or Kr is added to C2Br2F4 and SF6, the vertical shape can be acquired without generating the undercut. The addition of these gases displays an effect in which the bottom of a trench or a hole is rounded. When a phenomenon in which the trench or the hole is thinned suddenly is generated as the etching of the trench or the hole progresses through etching only of C2Br2F4+SF6, the vertical shape can be obtained by addition these gases.

Title: Production of high-purity high chromium alloy
Inventor: KATO YOSHINORI
IPC: C22B34/32
Filed: 1989-03-09
Abstract: PURPOSE:To economically produce a high-purity high chromium alloy by nitriding and crushing low carbon ferrochrome, adding acid solution while vigorously agitating the resulting grains in the acid solution and mixing the grains with the acid solution to perform iron removal, and then carrying out denitriding by means of vacuum heating. CONSTITUTION:Low carbon ferrochrome of >= about 50% Cr and <= about 1% C is crushed to <= about 5mm grain size and nitrided by a solid nitriding method. The resulting ferrochrome nitride is crushed to <=1mm grain size, and the grains obtained are subjected to acid treatment to undergo iron removal. The above acid treatment is carried out by agitating and mixing so that the ferrochrome nitride grains are suspended as a whole in the acid solution and also continuously adding the acid solution to perform reaction, by which impurities, such as Si, P, S, Ni, Co, and Mn, are removed simultaneously with the above iron removal. Subsequently, the ferrochrome nitride after iron removal is denitrided by means of vacuum heating, and simultaneously, C, N, O, etc., are removed. By this method, the high-purity high chromium alloy minimal in impurity content and having about 70-95% Cr content can be obtained by using relatively inexpensive material.
