Claim 0:
1. A substrate processing apparatus, comprising:
a heat plate configured to place a substrate thereon and heat the substrate placed thereon;
multiple gap members formed along a front surface of the heat plate on which the substrate is placed, and configured to support the substrate to secure a clearance between the heat plate and the substrate;
a suction unit configured to suck the substrate toward the heat plate;
an elevating pin configured to penetrate the heat plate and configured to be moved up and down to move the substrate placed on the heat plate up and down;
a base plate, configured to support the heat plate from below with a supporting member therebetween, having a path hole through which the elevating pin passes;
an upper seal member made of a cylindrical heat insulating material and in contact with a bottom surface of the heat plate opposite to the front surface; and
a lower seal member configured to close an internal space of the path hole of the base plate and an internal space of the upper seal member with respect to a space below the base plate,
wherein the front surface of the heat plate has a concave region inclined downwards from an outer side toward an inner side thereof.
