SOLUTION: The lower part electrode 4 is pattern-formed at respective pixels a on a substrate 2. An auxiliary wiring N with a constitution that is provided with a light-absorbing layer 9 composed of a conductive material having a higher light absorbance than that of the lower part electrode 4 is formed between respective pixels a. An organic layer 5 is formed in a state covering the lower part electrode 4 on the substrate 2 at which the lower electrode 4 and the auxiliary wiring N have been formed. Laser beam is converted into heat at the light absorbing layer 9 exposed to the lower part of the organic layer 5 by irradiation of the laser beam from the organic layer 5 side, and the organic layer 5 part on the upper part of the light absorbing layer 9 is selectively removed. The organic layer 5 is made to be pinched between the lower part electrode 4, and on the light absorbing layer 9 part where the organic layer 5 has been removed, the upper part electrode 6 connected to the auxiliary wiring N is formed on the substrate 2.

SOLUTION: An organic layer forming part 110 forming an organic layer, a second electrode forming part 120 forming a boundary layer and a second electrode, and a defect inspection part 130 inspecting defect in vacuum or in an inert gas atmosphere are combined through a middle chamber 140 and a base plate transferring mechanism 160 without being exposed in the air. A defect is inspected at the defect inspection part 130 after forming the organic layer at the organic layer forming part 110 and before forming the boundary layer and the second electrode. Defective base plates are selected and rejected from a defective base plate rejection outlet 130A before formation of a protection film which can not be peeled off, and the films are successively formed only on non-defective base plates. Film-forming is started again from the organic layer on the defective base plate, after a restoration treatment is applied for peeling off an organic layer with defects. The defect inspection may be carried out after the formation of the second electrode and before the formation of the protection film. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To prevent a mask for manufacturing organic EL elements from contacting a substrate and to maintain good arrangement position accuracy of deposited matter. SOLUTION: A mask holding part 200 for laminating and holding a fixing mask 101 and a moving mask 102 is provided to a mask device 1. The mask strength is realized by providing a plurality of masks. Only the moving mask 102 near a deposition source is slid with fixing the fixing mask 101 near the substrate without replacing the mask for every color or sliding the entire mask for the substrate. The mask holding part 200 has mechanism for giving a force from the side face of the moving mask 102 that does not directly contact the substrate, and thereby bending occurred vertically from the mask plane due to gravity or heat expansion can be canceled. Accordingly, the good positional accuracy of respective picture elements can be maintained even for a large screen. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To enhance resolution while keeping the dry etching resistance of the positive photoresist composition by using a specified photodecolorable compound as a dissolution preventer. SOLUTION: The positive photoresist composition to be used for far ultra-violet rays contains a (meth)acrylic polymer, an acid photogenerator, and the dissolution preventer which is at least one kind of photodecolorable compound selected from vitamin A group or a vitamin D group. This photodecolorable compound has a decolorability of a property of absorbing ultraviolet rays lowering at first, when it is exposed to far ultraviolet rays, especially, those of 193nm wavelength, and consequently, when the resist-coated film comprising this composition is exposed to the far ultraviolet rays, the light transmittance of the exposed part becomes higher than the surrounding unexposed part with the lapse of time, and the contrast of the transmittance between them increases, thus raising the resolution of the positive photoresist.
