Claim 0:
1. A temperature control device comprising:
a top plate configured to support a substrate;
a base plate that is connected to the top plate and defines an internal space with the top plate;
a thermoelectric module plate arranged in the internal space;
a heat exchange plate that is arranged in the internal space and configured to exchange heat with the thermoelectric module plate;
a first coupling member that couples the top plate and the base plate via the thermoelectric module plate and the heat exchange plate, the first coupling member having a first end that is configured to be fixed to the top plate and a second end that is configured to be fixed to the base plate; and
a second coupling member that couples the top plate and the base plate via the thermoelectric module plate and the heat exchange plate, the second coupling member having a first end that is configured to be fixed to the top plate; and
a sliding member arranged between the second coupling member and the base plate,
wherein the second coupling member has a second end that is configured, based on the first end of the second coupling member being fixed to the top plate, to move relative to the sliding member along a surface of the sliding member such that the second coupling member moves relative to the base plate,
wherein the base plate defines a concave portion that is recessed upward from a bottom surface of the base plate toward the top plate and accommodates a head portion of the second coupling member, the head portion defining the second end of the second coupling member,
wherein the temperature control device further comprises a first washer disposed between the sliding member and an upper surface of the concave portion, and
wherein an outer circumferential surface of the first washer and an outer circumferential surface of the sliding member are in contact with an inner circumferential surface of the concave portion in a radial direction.
