Claim 9:
10. A stage having an upper surface on which a substrate is placed, the stage comprising:
a temperature adjuster configured to perform at least one of heating and cooling to the substrate placed on the upper surface;
a through-hole vertically penetrating the stage; and
a lateral hole formed to extend from a side surface of the stage so as to intersect with the through-hole,
wherein a substrate support pin having a protrusion configured to protrude from the upper surface of the stage through the through-hole, and a large diameter portion located below the protrusion and formed thicker than the protrusion is inserted into the through-hole,
a support member is configured to engage with the large diameter portion of the substrate support pin to support the substrate support pin, and is inserted into the lateral hole, and
an upper opening end of the through-hole is thinner than the large diameter portion of the substrate support pin.
