Claim 13:
14. A substrate chuck for allowing one surface of a substrate to be in contact with a fluid in an assembly chamber, the substrate chuck comprising:
a first frame having a first hole at a central portion thereof;
a second frame having a second hole at a central portion thereof to overlap the first hole, and disposed to overlap the first frame;
a frame transfer part connected to the second frame and configured to vertically move the second frame with respect to the first frame; and
a sealing part disposed between the first hole and a sidewall portion of the first frame,
wherein the first frame comprises:
a bottom portion at which the first hole is formed; and
the sidewall portion formed on a peripheral edge of the bottom portion,

wherein a height of the sidewall portion is greater than a depth at which the substrate is placed into the fluid in the assembly chamber,
wherein the substrate is configured to be disposed between the first frame and the second frame,
wherein the first frame allows a lower surface of the substrate to be exposed through the first hole and the second frame allows an upper surface of the substrate to be exposed through the second hole,
wherein the sealing part is disposed between an upper surface of the first frame and a bottom surface of the second frame, and
wherein the sealing part surrounds the first hole.
