Abstract:
A method of measuring a position error of a beam of an exposure apparatus and an exposure apparatus using the same are provided. An exposure apparatus using a digital micromirror device (DMD) element instead of a mask measures a radiation amount of a beam that passes through each pinhole using a mask including a pinhole, and when the radiation amount is less than a reference value, it is determined that an exposure beam has a position error. By using the exposure apparatus and a method of measuring a position error of a beam, a measurement time period is reduced, and a position error of a beam is simply and accurately determined.

Abstract:
A method of planarizing a substrate. An organic layer is formed on a base substrate to cover a metal line formed on the base substrate. A portion of the organic layer is removed to form a pre-planarization layer exposing the metal layer, so that a surface of the base substrate having the metal line is planarized. The pre-planarization layer is cured to flow toward a side surface of the metal line to form a planarization layer making contact with the side surface of the metal line. Therefore, a stepped portion between the base substrate and the metal line can be minimized or substantially eliminated, thereby increasing the surface uniformity of a subsequent layer, thereby improving the reliability of the manufacturing process.

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.
