  • Publication number: 20100043708
    Abstract: A ceramic heater capable of reducing power consumption, a method of manufacturing the ceramic heater and an apparatus for forming a thin layer having the ceramic heater are disclosed. The ceramic heater includes a plate, a first heating layer, a second heating layer and a connecting member. The first and second heater layers are disposed parallel to each other within the plate. The connecting member includes a ceramic material having a negative temperature coefficient (NTC) to electrically connect the first heating layer with the second heating layer at a temperature higher than a predetermined target temperature.

  • Patent number: 6833279
    Abstract: Provided is a method of fabricating and repairing ceramic components for semiconductor fabrication, through which erosion and polymer deposition occurring on ceramic components for semiconductor fabrication are decreased by modifying the dielectric surface of a component having an electrical insulation characteristic so that the ceramic components can be repaired after being used. The method includes activating a surface layer of a component, which is manufactured by sintering a ceramic, and depositing a dielectric coating layer on the surface layer of the ceramic component using a plasma spray process; when the dielectric coating layer is damaged as the ceramic component is used for semiconductor fabrication, removing the dielectric coating layer; and repairing the ceramic component by depositing a dielectric coating layer on the surface layer of the ceramic component from which the damaged dielectric coating layer has been removed.
