Abstract:
1. A component in a processing chamber of a substrate processing apparatus, wherein a temperature of the component is measured, the component comprising: an abrasive surface which is exposed to an abrasive atmosphere and a nonabrasive surface which is not exposed to the abrasive atmosphere; a temperature measured portion including a surface at the abrasive surface side and a surface at the nonabrasive surface side, which are parallel to each other; and a coating portion which coats the surface of the temperature measured portion at the abrasive surface side, wherein the temperature measured portion is a thin-walled portion corresponding to a concave portion formed on the abrasive surface, and a mirror surface finishing is performed on each of a surface of the thin-walled portion at the abrasive surface side and a surface of the thin-walled portion at the nonabrasive surface side.
