Patent ID: 8052853

Claim:
A sputtering apparatus, comprising: a container; a plate for supporting the container; a first attachment for attaching the container to the plate; and a second attachment for attaching the container to the plate, the sputtering apparatus configured for attatching a container to a plate through a first container fixing hole provided at a front side of the container by screwing a first screw without forming a gap between a head portion of the screw and a first buffer; and the sputtering apparatus further configured for screwing the container only to the plate by sliding a second screw through a second container fixing hole provided at the front side of the container positioned opposite to the first container fixing hole, wherein the second container fixing hole is larger than the first container fixing hole, wherein including inserting a column portion of the second screw through the second container fixing hole and forming a head portion of the second screw integrally with the column portion, the head portion having a diameter larger than the diameter of the second container fixing hole, and wherein the column portion of the second screw has a diameter narrower than the diameter of the second container fixing hole thereby forming a gap between the head portion of the second screw and a second buffer, wherein both sides of the container is disposed on the plate, wherein the second container fixing hole is configured to prevent damage when the sputtering apparatus expands by heat, wherein a substrate is on the container, and wherein the first and second buffers are interposed between the container and the plate.
