Photosensitive composition and pattern formation method using the same. |
摘要 |
<p>This invention includes a photosensitive composition containing an alkali-soluble resin and a compound represented by formula (I), (II) or (III) described in the claims and the specification, a photosensitive composition containing an alkali-soluble polymer, a compound represented by formula (IV) described in the claims and the specification and a basic compound, and a photosensitive composition containing an alkali-soluble polymer, a compound represented by formula (VI) described in the claims and the specification and a compound which produces an acid upon radiation of light. A pattern formation method using these photosensitive compositions includes the steps of dissolving any one of the above photosensitive compositions in an organic solvent to prepare a photosensitive resin solution, coating the photosensitive resin solution on a substrate to form a photosensitive resin layer on the substrate, pattern-exposing the photosensitive resin layer, and developing the exposed resin layer with an aqueous alkaline solution. When the first or second photosensitive composition is used, a good pattern can also be formed by a method including the steps of dissolving either the first or second photosensitive composition in an organic solvent to prepare a photosensitive resin solution, coating the photosensitive resin solution on a substrate to form a photosensitive resin layer on the substrate, pattern-exposing the photosensitive resin layer, heating the pattern-exposed resin layer, exposing the entire surface of the heated resin layer, and developing the entirely exposed resin layer with an aqueous alkaline solution.</p> |
