  • Patent number: 8643845
    Abstract: Provided are a surface inspection apparatus and method capable of detecting foreign materials on the surface of a substrate, and a slit coater having the surface inspection apparatus. In the surface inspection apparatus, a slit lighting unit irradiates slit-shaped light. An optical system splits the slit-shaped light into two beams traveling along two different paths, is incident upon a subject, and extracts an interference image caused by combination of the two beams reflected from the subject. An imaging device captures the interference image to output an image signal. An analysis unit acquires a luminance value of the image signal, analyzes the luminance value in real time, and determines whether or not foreign materials are present.

  • Patent number: 8389323
    Abstract: Provided are a method of manufacturing an organic light emitting display apparatus, a surface treatment device for an organic light emitting display apparatus, and an organic light emitting display apparatus. To easily form organic emissive layers, the method includes: forming a first electrode on a substrate; forming on the first electrode a pixel defining layer having openings that expose predetermined portions of the first electrode; forming a charge carrying layer on the pixel defining layer and the first electrode exposed through the openings; hydrophobically treating portions of a surface of the charge carrying layer selectively, wherein the portions do not correspond to the openings, using a laser; forming organic emissive layers on the charge carrying layer; and forming a second electrode on the organic emissive layers so as to be electrically connected with the organic emissive layers.

  • Patent number: 8206549
    Abstract: An etching apparatus includes: an etching chamber; a piping unit disposed in an upper portion of the etching chamber and including a plurality of nozzles via which an etchant is sprayed; a substrate mask disposed below the piping unit; and a transfer unit disposed below the substrate mask and used to transfer a substrate. The substrate mask interposed between the piping unit including the nozzles and the substrate has a mesh structure or a plurality of holes or slits. Thus, the generation of microbubbles can be prevented during a wet etching process so that a thin layer formed on the substrate can be etched at a uniform etch rate. Also, a lift unit having a fixing unit may be disposed on a lateral surface of the substrate mask. The lift unit moves the substrate mask up and down so as to obtain a uniform etch rate.
