Claim:
1. A manufacturing method of a mask for deposition, the manufacturing method comprising: forming a second layer on a side of a first layer; coating a photoresist layer on a side of the second layer, and forming a plurality of photoresist patterns, which penetrate the photoresist layer according to an exposing and developing process; forming a plurality of pattern grooves in the second layer by etching portions of the second layer which are exposed through the plurality of photoresist patterns; forming an electro-forming mold by removing the photoresist layer from the second layer; disposing an electrode plate to contact the second layer of the electro-forming mold; performing an electro-forming process of growing a metal layer from the electrode plate in spaces in the corresponding pattern grooves of the second layer of the electro-forming mold, to form a deposition mask; and separating the deposition mask from the electrode plate.
