There are provided a coating material which improves an etching resistance of a pattern in an etching process using a pattern formed on a substrate as a mask.The material is a pattern coating material for an etching process using a pattern formed on a substrate as a mask, including a metal compound (W) which can produce a hydroxyl group on hydrolysis.
摘要:
A positive type resist composition for forming a high resolution resist pattern and a method of forming a resist pattern are provided which use a low-molecular-weight material as a base component, and a compound and a dissolution inhibitor that are each suitable for the positive type resist composition. Here, the compound is a non-polymer having a molecular weight of 500 to 3000, and is decomposed under the action of an acid to produce two or more molecules of a decomposition product having a molecular weight of 200 or more; the dissolution inhibitor comprises the compound; the positive type resist composition comprises the compound and the acid generator component; and the method of forming a resist pattern uses the positive type resist composition.

摘要:
A pattern-forming method, including: forming a first resist film by applying a first chemically amplified resist composition onto a support, forming a plurality of resist patterns by selectively exposing and then developing the first resist film, forming a plurality of coated patterns by forming a coating film composed of a metal oxide film on the surface of each resist pattern, forming a second resist film by applying a second chemically amplified resist composition onto the support having the coated patterns formed thereon, and selectively exposing and then developing the second resist film, thereby forming a pattern composed of the plurality of coated patterns and a resist pattern formed in the second resist film onto the support.

摘要:
This resist composition is a resist composition containing a compound in which a portion or all of hydrogen atoms of phenolic hydroxyl groups in a polyhydric phenol compound (a) having two or more phenolic hydroxyl groups and having a molecular weight of 300 to 2,500 are substituted with at least one selected from the group consisting of acid dissociable dissolution inhibiting groups represented by the following general formulas (p1) and (p2) wherein R1 and R2 each independently represents a branched or cyclic alkyl group, and may contain a hetero atom in the structure; R3 represents a hydrogen atom or a lower alkyl group; and n′ represents an integer of 1 to 3.
