    摘要: Provided is a method of forming micropatterns, in which a line-and-space pattern is formed using a positive photoresist, and a spin-on-oxide (SOX) spacer is formed on two sidewalls of the line-and-space pattern and used in etching a lower layer, thereby doubling a pattern density. Accordingly, all operations may be performed in single equipment (lithography equipment) without taking a substrate out, and thus a high throughput is obtained, and concerns about pollution are very low. Moreover, as the line-and-space pattern is formed using a wet method by using a negative tone developer, line-width roughness (LWR) of the micropatterns may be improved compared to when a dry etching method is used.

    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.
