    摘要: The present invention provides a double photolithography method in which, after a first photoresist pattern including a crosslinkable agent is formed on a semiconductor substrate, a crosslinkage is formed in a molecular structure of the first photoresist pattern. A second photoresist film may be formed on a surface of the semiconductor substrate on which the crosslinked first photoresist patterns are formed. Second photoresist patterns may be formed by exposing, post-exposure baking, and developing the second photoresist film.

    摘要: In a method of forming a metal or metal nitride pattern, a metal or metal nitride layer is formed on a substrate, and a photoresist pattern is formed on the metal or metal nitride layer. An over-coating composition is coated on the metal or metal nitride layer and on the photoresist pattern to form a capping layer on the photoresist pattern. The over-coating composition includes a polymer having amine groups as a side chain or a branch and a solvent. A remaining portion of the over-coating composition is removed by washing with a hydrophilic solution. The metal or metal nitride layer is partially removed using the capping layer and the photoresist pattern as an etching mask.
