Patent number: 11987740Abstract: Provided are a silicon nitride film etching composition, a method of etching a silicon nitride film using the same, and a manufacturing method of a semiconductor device. Specifically, a silicon nitride film may be highly selectively etched as compared with a silicon oxide film, and when the composition is applied to an etching process at a high temperature and a semiconductor manufacturing process, not only no precipitate occurs but also anomalous growth in which the thickness of the silicon oxide film is rather increased does not occur, thereby minimizing defects and reliability reduction.Type: GrantFiled: August 30, 2021Date of Patent: May 21, 2024Assignee: ENF Technology Co., Ltd.Inventors: Dong Hyun Kim, Hyeon Woo Park, Sung Jun Hong, Myung Ho Lee, Myung Geun Song, Hoon Sik Kim, Jae Jung Ko, Myong Euy Lee, Jun Hyeok Hwang
