Abstract
The present invention is a boat for a thermal process including: a plurality of pillars; a plurality of claws formed in each of the pillars in a height direction at predetermined intervals; a plurality of supporting plates mounted in a tier-like manner between the plurality of pillars via the claws, each supporting plate having an object-to-be-processed mounting surface on which an object to be processed can be mounted; and a groove and a through hole provided in the object-to-be-processed mounting surface. According to the present invention, the groove and the through hole provided in the object-to-be-processed mounting surface form an air layer between the object-to-be-processed mounting surface of the supporting plate and the object to be processed, so that sticking of the object to be processed can be inhibited. Thus, even during a thermal process at a high temperature, generation of slip caused by the sticking of the object to be processed can be inhibited.
