Patent ID: 8267253

Claim:
A carrier for a sputtering apparatus for transporting a substrate comprising: a frame with a substantially planar upper surface configured to support a substrate, the upper surface defines a through-hole at a center, wherein the through-hole includes a first inner surface and a second inner surface that faces the first inner surface in the through-hole; a plurality of support bars each joined to the first inner surface and the second inner surface and having free movement at the joined portion; first and second grooves formed at the first and second inner surfaces; and first and second elastic units joined to both ends of each support bar, wherein the support bars are disposed below a lower surface of the substrate; wherein each support bar is inserted into the first and second grooves, wherein each elastic unit includes: a joining member engaged with the support bar in the through-hole through a hole near each inner surface; an elastic member configured to surround the joining member for controlling a movement of the joining member; and a plurality of sub bars that project from the support bars in a direction that is substantially transverse to a longitudinal axis of the support bars by a first distance and that are separated from neighboring sub bars by a second distance, wherein top surfaces of the sub bars are substantially in the same plane as the planar top surface of the frame so as to support the lower surface of the substrate.
