Abstract: The present invention provides a substrate heat treatment apparatus capable of uniformly heat a substrate at high speed with less breakage of constituent members due to thermal expansion even at high temperature. An embodiment of the present invention is a substrate heat treatment apparatus to perform heat treatment for a substrate and includes: a peripheral ring capable of supporting the substrate; a connection ring; a lifting device to raise and lower the peripheral ring balls having a lower heat conductivity than that of the peripheral ring; and a lamp to heat the substrate supported by the peripheral ring. The balls are different members from both of the peripheral ring and the connection ring. The lifting device raises and lowers the peripheral ring between a first position close to the lamp and a second position distant from the lamp.
