  • Patent number: 6893791
    Abstract: Disclosed is a photoresist composition having a good sensitivity and residual layer characteristic and a method of forming a pattern using the same. The photoresist composition includes 5-30% by weight of a polymer resin, 2-10% by weight of a photosensitive compound, 0.1-10% by weight of a sensitivity enhancing agent, 0.1-10% by weight of a sensitivity restraining agent and 60-90% by weight of an organic solvent. A photoresist layer is formed by coating the photoresist composition on a substrate and then drying the coated photoresist composition. Then, thus obtained photoresist layer is exposed by using a mask having a predetermined pattern. Then, a photoresist pattern is formed by developing thus exposed photoresist layer. The photoresist pattern exhibits a uniform layer thickness and critical dimension.

  • Publication number: 20050089790
    Abstract: A photoresist composition for a spinless coater includes a novolak resin having a weight average molecular weight of about 2,000 to about 15,000, a diazide based photosensitive compound and a volatile organic solvent. The photoresist composition is applied to a substrate of a liquid crystal display apparatus to reduce blots and enhance application uniformity. A highly volatile solvent, such as n-propyl acetate (nPAC) or n-butyl acetate (nBA) is used in the photoresist composition as the volatile organic solvent. The photoresist composition including the volatile organic solvent gives a photoresist film that has a uniform thickness. Hence, the generation of small resin blots and thick blots may be reduced.

  • Publication number: 20040253541
    Abstract: The present invention relates to a photoresist composition having high heat resistance used in the production process of an LCD, and more particularly, to a photoresist composition having high heat resistance, capable of decreasing process tact (a way), of process simplification, and of the retrenchment of expenditures. The inventive composition facilitates this through making it possible to skip 5 processes, such as Cr metal deposition forming a metal film, and the photo/etch/PR strip/etch steps of the whole surface of the metal, by substituting the inventive composition for the usual metal film, such that N+ ion doping in production of a TFT-LCD can take place due its high heat resistance.

  • Patent number: 6686120
    Abstract: Disclosed is a photoresist composition including a thermal acid generator and a method of forming a pattern using the same. The photoresist composition includes about 100 parts by weight of an alkali-soluble acryl copolymer, about 5-100 parts by weight of 1,2-quinonediazide compound, about 2-35 parts by weight of nitrogen-containing cross-linking agent and about 0.1-10 parts by weight of a thermal acid generator which produces an acid by heat. The photoresist composition is coated on a substrate and dried to form a photoresist layer. The photoresist layer is exposed by using a mask having a predetermined shape. Thus obtained exposed photoresist layer is developed by using an aqueous alkaline solution to form a photoresist pattern. Thus obtained photoresist pattern is heated to be cured without generating thermal reflow.

  • Publication number: 20030194727
    Abstract: In one aspect, a library of nucleic acids that encode different artificial, chimeric proteins is screened to identify a chimeric protein that alters a phenotypic trait of a cell or organism. The chimeric protein can be identified without a priori knowledge of a particular target gene or pathway. Some chimeric proteins include multiple zinc finger domains and can induce, for example, thermotolerance, solvent-tolerance, altered cellular growth, insulin production, differentiation, and drug resistance.
