Patent number: 6565662Abstract: A plasma etching apparatus includes a process container formed of a container main body and an upper casing combined with each other. A detaching device is provided to move the upper casing between a mounted position where the upper casing is put on the container main body, and a retreated position where the upper casing is removed from the container main body. The detaching device supports the upper casing to be rotatable, movable up and down, and movable in a lateral direction, relative to the container main body. The retreated position is arranged such that the upper casing does not interfere with the container main body when the upper casing is rotated there.Type: GrantFiled: December 20, 2000Date of Patent: May 20, 2003Assignee: Tokyo Electron LimitedInventors: Kenji Amano, Yoshitsugu Tanaka
