Abstract

PURPOSE: To facilitate maintenance upon occurrence of a dislocation of a thermal stress at the time of treating a large-diameter wafer at a high temperature, damage or deformation of a wafer holder and to further prevent a local application of a load to the vicinity of the holder by employing a member in contact with the wafer, having the same physical properties as those of the wafer.
CONSTITUTION: A boat body in which a top plate 1 and a bottom plate 2 made of quartz or SiC are integrated by connecting round rods 3a, 3b, 3c of the same material by welding, of a boat used for a vertical bottom-open type heat treating device, is obtained, groove rods 4a, 4b, 4c, 4d having grooves 5a formed at a predetermined interval in a longitudinal direction and the same physical properties as those of a wafer are detachably mounted between the plates 1 and 2, and the wafer is supported to the grooves 5a of the rods 4a-4d.
