Claim 9:
10. A mask frame comprising:
a first horizontal portion;
a second horizontal portion disposed under the first horizontal portion;
at least one vertical portion connecting the first horizontal portion and the second horizontal portion; and
a first tensile bar coupled to a first part of the first horizontal portion;
a second tensile bar coupled to a second part of the first horizontal portion that is different than the first part,
wherein the first tensile bar is spaced apart from the second tensile bar with respect to a cross sectional view of the mask frame such that a gap exists between the first tensile bar and the second tensile bar,
wherein a tensile force of the first tensile bar and a tensile force of the second tensile bar are such that a first edge of the first tensile bar and a first edge of the second tensile bar are urged to move in a direction towards each other, and
wherein the tensile force of the first tensile bar and the tensile force of the second tensile bar are such that a second edge of the first tensile bar opposite the first edge of the first tensile bar, and a second edge of the second tensile bar opposite the first edge of the second tensile bar, are urged to move in a direction away from each other.
