Claim 0:
1. 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 and disposed to overlap the first frame, wherein the first frame comprises:
a bottom portion at which the first hole is formed; and
a sidewall portion formed on a peripheral edge of the bottom portion; and

a frame transfer part connected to the second frame and configured to vertically move the second frame with respect to the first frame,
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 first frame comprises a sealing part disposed at an edge of the first hole,
wherein the first frame and the second frame are configured to be disposed at a first side and a second side of the substrate, respectively with the substrate interposed therebetween, and
wherein the frame transfer part is configured to transfer the second frame so that a first surface of the substrate is in contact with the fluid while the second frame presses on a second surface of the substrate.
