Abstract:
A member for a semiconductor manufacturing apparatus includes a ceramic disc incorporating an electrode and a ceramic cylindrical shaft supporting the disc. The disc and the shaft are integrally formed and mutually have no bonding interface. The disc has a surface with which the shaft is integrated. The surface has a region inside the shaft and a region outside the shaft. The region inside the shaft is recessed by one step with respect to the region outside the shaft and has an electrode exposure hole through which the electrode is exposed.
