    摘要: Provided is a method of manufacturing a display substrate. In the method, a gate line, a data line crossing the gate line, and a switching device are formed on a base substrate. A passivation layer, a first resist layer and a second resist layer are formed on the base substrate. The first resist layer and the second resist layer are patterned to form a resist pattern and an etch-stop pattern, the etch-stop pattern having a sidewall protruding from a sidewall of the resist pattern. A portion of the passivation layer is removed to form a contact hole on a drain electrode of the switching device. A pixel electrode electrically connected to the switching device through the contact hole is formed. Thus, an undercut between an etch-stop pattern and a resist pattern may be more easily formed without over-etching a passivation layer.

    摘要: A halftone mask includes a transparent substrate, a light-blocking layer, a first semi-transparent layer and a second semi-transparent layer. The transparent substrate includes a light-blocking area, a light-transmitting area, a first halftone area transmitting first light, and a second halftone area transmitting second light that is less than the first light. The light-blocking layer is formed in the light-blocking area to fully block light from being transmitted. The first and second semi-transparent layers are formed on the transparent substrate. At least one of the first and second semi-transparent layers is formed in the first halftone area, and the first and second semi-transparent layers are overlapped with each other on the second halftone area.

The micro lens part is disposed between the stage and the digital micro mirror part and includes a plurality of micro lenses. The micro lenses convert the one or more second light beams into one or more third light beams which are irradiated upon the substrate. The third light has an oval cross sectional shape.

    摘要: An apparatus and a method for determining an overlap distance of an optical head is disclosed. Positions and light amount distributions of each light spot can be measured, which may be provided from an optical head to a substrate. Gaussian distribution may be applied to the positions and the light amount distributions to calculate a compensation model of each of the light spots. A first accumulated light amount corresponding to each first area of the substrate may be calculated if the optical head is scanning along a first direction of the substrate using the compensation model. A second accumulated light amount corresponding to each second area overlapped with the each first area is calculated if the optical head is scanning along the first direction, which is moved in a second direction by a first distance using the compensation model. An overlap distance may be determined based on a uniformity of summations of the first and second accumulated light amount.

    摘要: A digital exposure method and a digital exposure device for performing the method are disclosed. In the method, a graphic data system file is produced in correspondence with each of a plurality of patterns formed on a substrate. Then, a digital micromirror device on/off data is generated from the graphic data system file. Then, the substrate is exposed in response to the digital micromirror device on/off data. Thus, at least a first exposure for forming a first pattern of a display panel, and a second exposure for forming identification numbers of a substrate and each display panel and removing an edge portion of the substrate may be simultaneously performed, to simplify the exposure process decrease costs.
