A focus ring heat transfer method improves heat transfer of a focus ring arranged in an outer peripheral portion of a mounting surface of a mounting table adapted to mount a target substrate in a chamber. The method includes steps of: disposing a heat transfer sheet between the focus ring and the mounting table; and vacuum-evacuating the chamber prior to processing the target substrate and then restoring the pressure the inside of the chamber to an atmospheric pressure or a light vacuum pressure. Therefore, air present in a fine gap between the heat transfer sheet and the mounting surface is removed to allow the heat transfer sheet to adhere to the mounting surface.
