Abstract:
A mask manufacturing apparatus includes a chamber, a laser beam irradiator, a stage, a cooling system, and a fan. The chamber provides an interior space therein. At least an upper wall of the chamber comprises a glass. The laser beam irradiator is disposed outside the chamber and configured to divide a laser beam into a plurality of sub-laser beams to irradiate the sub-laser beams onto a shadow mask material. The stage is disposed in the chamber and the shadow mask material is placed on the stage. The cooling system is configured cool the interior space. The fan configured to discharge heat generated in the interior space of the chamber to the outside of the chamber. Therefore, the shadow mask may be protected from overheating.
Abstract:
A mask substrate that includes a first area and a second area surrounding the first area is provided. Then, a laser beam is irradiated on the mask substrate to at least partly remove a material of the second area. After that, a physical force is applied to the mask substrate to separate the first area from the mask substrate thereby forming an opening through the mask substrate.
Abstract:
A laser processing apparatus includes: a laser generator that generates a laser beam, a diffractive optical element that divides the laser beam generated by the laser generator into a plurality of sub-laser beams, and a beam gap adjustor that adjusts a gap between neighboring ones of the plurality of sub-laser beams. Therefore, by installing a diffractive optical element that divides a laser beam that is generated by the laser generator into the plurality of sub-laser beams and a beam gap adjustor to adjust a gap between a plurality of sub-laser beams, the laser processing apparatus can form a processing pattern of various resolutions in a shadow mask while improving a processing speed of the shadow mask.
Abstract:
A mask manufacturing apparatus includes a laser irradiator, a stage, a frame, and a heat spreader sheet. The laser irradiator divides a laser beam into a plurality of sub-laser beams and irradiates the sub-laser beams to a shadow mask material which is placed over a stage. The frame is disposed over the stage to support the shadow mask material. The heat spreader sheet makes contact with the shadow mask material, absorbs heat generated from the shadow mask material, and dissipates the heat to surroundings of the shadow mask material. Accordingly, the shadow mask material is protected from overheating.
