Patent ID: 8052850

Claim:
A method of operating a sputtering apparatus, which includes a substrate on a susceptor, a first target device having an elongated shape in a first direction and disposed on a first region of the substrate opposite to a center region of a substrate, at least second and third target devices each having an elongated shape in a second direction perpendicular to the first direction and disposed on second and third regions of the substrate opposite to opposite first and second side regions of the substrate, and at least fourth and fifth target devices each having an elongated shape in the first direction and disposed on fourth and fifth regions of the substrate opposite to opposite third and fourth side regions of the substrate, the method comprising: rotating each of the second and third target devices and each of the fourth and fifth target devices clockwise during a first operating period; and rotating each of the second and third target devices and each of the fourth and fifth target devices counterclockwise during a second operating period, wherein the second and third target devices are rotated with respect to first axes parallel to the second direction and the fourth and fifth target devices are rotated with respect to second axes parallel to the first direction.
