METHOD OF HYDRATING A CERAMIC SPRAY-COATING LAYER, METHOD OF MANUFACTURING AN ELECTROSTATIC CHUCK THAT USES THE HYDRATING METHOD, AND SUBSTRATE STRUCTURE AND ELECTROSTATIC CHUCK HAVING THE CERAMIC SPRAY-COATING LAYER FORMED USING THE HYDRATING METHOD

摘要

In a method of hydrating a ceramic spray-coating layer of an electrostatic chuck, water penetrates into pores and/or cracks of the ceramic spray-coating layer, and the penetrated water then reacts with the ceramic spray-coating layer to form hydroxide in the pores and/or cracks. As a result, the electrical characteristics and hydrophobicity of the ceramic spray-coating layer may be improved.
