Claim Text:
1. A method of manufacturing a mask substrate, comprising: positioning a first conductive member on a base substrate; positioning a second conductive member on the first conductive member, the second conductive member being electrically coupled to the first conductive member, and having a resistivity higher than that of the first conductive member; positioning a mask substrate on the second conductive member; burning a portion of the mask substrate that contacts the second conductive member to remove the portion of the mask substrate and form a mask hole; and removing the base substrate, the first conductive member, and the second conductive member from the mask substrate after burning the portion of the mask substrate, wherein the mask hole is configured to control the deposition of an organic material through the mask hole onto an array substrate, wherein the mask substrate is formed of a material different from the organic material that is deposited onto the array substrate, and wherein burning the portion of the mask substrate comprises transmitting a current to the second conductive member through the first conductive member to generate heat from the second conductive member.
