Abstract
A heat treatment apparatus comprises: a chamber; a cooling plate and a heating plate disposed within the chamber vertically spaced from each other; plural lift pins used to support a material to be treated; a supporting member for supporting the plural lift pins; and an elevator member to which the supporting member is attached through a joint so that the supporting member can be selectively made rotatable and can be fixed at any inclined angle, wherein distances of tips of each of the lift pins from the heating or cooling plate are initially adjusted to be uniform through inclination of the supporting member while the tips contact the heating or cooling plate, after which the supporting member is fixed in an adjusted inclined angle and then the material to be treated is lifted up with the plural lift pins to closely approach the heating or cooling plate during heat treatment.
