Title: Method for preparing etching composition for silicon nitride
Inventor: SEONGHWAN PARK
IPC: C09K13/06
Filed: 2019-04-24
Abstract: Disclosed is a method for preparing an etchant composition for a silicon nitride film using a phosphoric acid esterification reaction. According to the method for preparing the etchant composition for the silicon nitride film, the phosphoric acid esterification reaction is performed through a pretreatment step of making an alcohol solution react with a solution containing phosphoric acid, such that the alcohol solution is uniformly mixed with a silane-based compound thereafter. Accordingly, the silane-based compound may be prevented from vaporized due to phase separation, thereby improving the manufacturing yield rate. As the pH of the phosphoric acid is increased by performing the phosphoric acid esterification reaction, the reaction speed may be adjusted when reacting with the silane-based compound, thereby preventing the molecular weight of a silylphosphine oxide compound and a silylphosphine compound from being rapidly largely increased. The yield rate and the lifespan of the silylphosphine oxide compound and the silylphosphine compound may be increased at a final stage.
