摘要:
Embodiments of the present invention generally relate to heated substrate supports having a protective coating thereon. The protective coating is formed from pure yttria or alloys predominantly of yttria. The protective coating is diffusion bonded to the heater plate of the substrate support. Two distinct silicon containing layers are formed between the heater plate and the protective coating as the result of the diffusion bonding.

摘要:
An aluminum nitride sintered compact, characterized in that (1) it contains sulfur and (2) it comprises ceramic particles having an average particle size of 3 mu m or less and, when ruptured, exhibits the state of rupture in the interior of particles; and a ceramic substrate comprising the aluminum nitride sintered compact and an electrically conductive material formed on the surface of or inside the ceramic. The aluminum nitride sintered compact has excellent mechanical strength and is free from occurrence of the particle phenomenon due to the fallout of ceramic particles from the surface or the side face thereof, and therefore, is suitably used for a ceramic substrate for use in a device for the manufacture or inspection of semiconductors, such as a ceramic heater or an electrostatic chuck.
