Abstract:
A heat treatment container ( 1 ) is provided with support members ( 6 ) for supporting a disc-shaped SiC substrate ( 2 ), which is an object, at a time of an etching treatment of the SiC substrate ( 2 ). Each of the support members ( 6 ) has an inclined surface ( 6 F) for supporting a lower surface end ( 2 E) of the SiC substrate ( 2 ), the inclined surface being inclined so as to increasingly approach the centerline of the SiC substrate ( 2 ) going downward. More specifically, each of the support members ( 6 ) is formed in a conical shape with a diameter that increases going downward, and a conical surface which is the peripheral surface of each supporting member forms the inclined surface ( 6 F). A vertically-middle section of the inclined surface ( 6 F) contacts the lower surface end ( 2 E) of the SiC substrate ( 2 ).

Claim (Index 4):
The heat treatment container according to  claim 3 , wherein\n each of the supporting members is made of tantalum carbide or niobium carbide, an inner bottom surface of the bottom plate and a surface that exposes to an internal space of the heat treatment container are made of tantalum silicide.
