Claim Text:
1. A system including an apparatus configured to fix a metal mask between an evaporation source and a substrate, the apparatus comprising: a first substrate; a magnet array structure including a plurality of magnets disposed on the first substrate, the plurality of magnets including a plurality of magnetic axes, respectively, the plurality of magnetic axes crossing each other; a second substrate disposed on the magnet array structure; and a metal mask disposed on the second substrate, said metal mask comprises a patterned region having a plurality of openings and a frame region contacting the second substrate, wherein an upper surface of the magnet array structure is in direct contact with the first substrate, and the second substrate is disposed between a lower surface of the magnet array structure and the metal mask, wherein the magnet array structure comprises a first magnet, a second magnet, a third magnet, a fourth magnet, and a fifth magnet sequentially arranged on the first substrate, wherein a positive pole direction of the first magnet is defined as a first direction, a positive pole direction of the second magnet is defined as a second direction which intersects the first direction, a positive pole direction of the third magnet is defined as a third direction which intersects the second direction, a positive pole direction of the fourth magnet is defined as a fourth direction which intersects the first direction and the second direction, and a positive pole direction of the fifth magnet is defined as the first direction, wherein the first, third, and fifth magnets each have a magnetic axis perpendicular to a planar surface of the first substrate, the planar surface of the first substrate facing the first, second, third, fourth and fifth magnets, and wherein the second and fourth magnets having a magnetic axis parallel to the planar surface of the first substrate, and said system is configured to form a thin film on a patterned region of the second substrate.
