Patent number: 11404283Abstract: A method for etching a ruthenium film includes a first step of etching the ruthenium film by plasma processing using oxygen-containing gas, and a second step of etching the ruthenium film by plasma processing using chlorine-containing gas. The first step and the second step are alternately performed. In the first step and the second step, the ruthenium film is etched at a target control temperature for a target processing time that are determined based on a pre-obtained relation between an etching amount per one cycle including the first step and the second step as a set, a control temperature of the ruthenium film, and processing times of each of the first step and the second step.Type: GrantFiled: September 4, 2020Date of Patent: August 2, 2022Assignee: TOKYO ELECTRON LIMITEDInventors: Shigeru Tahara, Nobuaki Seki, Takahiko Kato
