  • Patent number: 11404283
    Abstract: 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.

  • Patent number: 10821916
    Abstract: An automotive interior component includes a base member including a front surface, a back surface, and a side surface provided between the front surface and the back surface; and a skin material integrated with the base member. The skin material is integrated with the front surface and the side surface. The side surface of the base member is continuous to the front surface of the base member while forming an acute angle of angle ? therewith. The skin material includes an end surface extending along the side surface of the base member. The present invention provides the automotive interior component with a neat appearance.
