Abstract
A vertical thermal processing apparatus including: a substrate supporter; a transfer mechanism to transfer substrates between the substrate supporter and a container; and a thermal processing furnace to process substrates that have been loaded thereinto with the substrate supporter. The substrate supporter includes: support columns located at intervals therebetween to surround the substrates, supporting parts for substrate and supporting parts for annular plate provided at the support columns in a tier-like manner, for alternately supporting peripheral parts of the substrates and of annular plates at predetermined intervals therebetween, and annular plates to be supported by the supporting parts for annular plate, when seen from a direction in which the substrates are transferred. Each of the annular plates has an intermediate part having a thickness smaller than thicknesses of the peripheral parts thereof to be supported by the support columns.
