Abstract:
1. A sputtering apparatus comprising: a susceptor for receiving a substrate; 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; wherein each of the second and third target devices rotates to a first orientation angle in a first direction and rotates to a second orientation angle in a second direction opposite to the first direction, wherein the fourth and fifth target devices rotate in opposite directions from each other to third and fourth orientation angles, and 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.
