Claim 0:
1. A substrate processing apparatus for processing a substrate, comprising:
a stage including a through-hole vertically penetrating the stage, the substrate being placed on an upper surface of the stage, and at least one of heating and cooling being performed on the substrate;
a substrate support pin inserted into the through-hole; and
a support member configured to support the substrate support pin,
wherein the substrate support pin has a protrusion configured to protrude from the upper surface of the stage through the through-hole of the stage, and a large diameter portion located below the protrusion and formed thicker than the protrusion, and
the stage further includes a lateral hole formed to extend from a side surface of the stage so as to intersect with the through-hole, and
the support member is inserted into the lateral hole,
the support member is configured to support the substrate support pin by an engagement with the large diameter portion of the substrate support pin while the support member is inserted into the lateral hole of the stage, and
an upper opening end of the through-hole of the stage is thinner than the large diameter portion of the substrate support pin.
