A method of cleaning off organic deposition material accumulated on a mask includes forming an organic deposition material pattern on a substrate using the mask, which includes a plurality of slots, in a deposition chamber including a deposition source; transporting the mask to a stock chamber that is maintained at a vacuum and adjacent to the deposition chamber; and partially cleaning off the organic deposition material accumulated along the boundaries of the slots of the mask in the stock chamber. A system to clean off an organic deposition material accumulated on a mask having a plurality of slots, includes a deposition chamber including a deposition source; and a stock chamber that is maintained at substantially the same vacuum as the deposition chamber and includes a cleaning device that cleans off the organic deposition material accumulated on the mask.

Method and apparatus for cleaning organic deposition materials

A method of efficiently manufacturing a large-sized mask is disclosed. In one embodiment, the method includes: 1) providing a first mask member comprising i) a first pattern unit having a plurality of slits, ii) a first buffer unit spaced apart from the first pattern unit, and iii) a first bonding unit interconnecting the first pattern unit and the first buffer unit and 2) providing a second mask member comprising i) a second pattern unit having a plurality of slits, ii) a second buffer unit spaced apart from the second pattern unit, and iii) a second bonding unit interconnecting the second pattern unit and the second buffer unit. The method may further include contacting the first bonding unit and the second bonding unit; and connecting the first mask member to the second mask member while tensile forces are applied to the first mask member and the second mask member.

Mask, method of manufacturing mask and apparatus for manufacturing mask

A mask frame assembly for thin film deposition includes a frame having an opening and at least two unit masks having end parts in a longitudinal direction fixed to the frame, each of the unit masks comprising first regions and second regions, the first regions having unit masking patterns, each of the unit masking patterns having a plurality of openings for thin film deposition, the unit masking pattern being spaced apart from each other, each of the second regions being interposed between a pair of adjacent ones of the first regions, the first regions having a first thickness from a first surface of the unit masks, and at least a portion of the second regions having a second thickness from a second surface of the unit masks opposite to the first surface of the unit masks, such that the first regions and the at least the portion of the second regions are offset from each other in a direction normal to the first and second surfaces. A plurality of unit masks are each half etched from different surfaces and thus a height of wrinkles generated in the mask of the mask frame assembly may be reduced.
