Abstract:
A method of producing a jig for semiconductor wafer, said jig having a wafer loading face, at least said wafer loading face being subjected to a treatment comprising the steps offorming a silicon carbide (SiC) film on a substrate for manufacturing the jig by applying a CVD method;grinding said silicon carbide (SiC) film by means of a silicon carbide (SiC) tool to smooth the jig;heat treating said smoothed jig in a high temperature oxygen gas so as to convert silicon carbide (SiC) particles produced in said silicon carbide (SiC) forming step and adhering to the surface of the jig into silicon dioxide (SiO.sub.2) particleswashing said jig in a solution until the silicon dioxide (SiO.sub.2) particles are dissolved therein.
