HEAT TREATMENT DEVICE AND METHOD OF MANUFACTURING SUBSTRATE

摘要

A heat treatment device and a method of manufacturing substrates capable of reducing the slippage of the substrates when the substrates are supported on support parts comprising plate-like members. The device comprises a support device (30) having the support parts (58) in contact with the substrates (54) and a body part (57) supporting the support parts (58). Each of the support parts (58) comprises the plate-like members supporting the substrate (54) so as not to come into contact with the peripheral edge portion of the substrate (54), and a non-contact part (70) communicating with the outside without coming into contact with the substrate (54) is formed in the substrate placing surface of the support part (58). The overall opening area of the portion of the non-contact part communicating with the outside is 25 to 94% of the overall area of the substrate placing surface.
