摘要:
Provided is a polymer useful as a base resin of a resist material featuring a high resolution, patterns with less sidewall roughness, practically acceptable etching resistance, and a substantial margin allowed for heat treatment temperature after exposure. The polymer has a weight-average molecular weight of from 1,000 to 50,000 and comprises at least one repeating unit of formula (1) below, at least one repeating unit of formula (2) below and at least one repeating unit of formula (3) below. A resist material comprising the polymer is also provided. In addition, provided is a pattern formation process comprising steps of applying the resist material onto a substrate, heating the film, exposing the heated film through a photomask to high energy radiation or electron beam, heating the exposed film and then developing with a developer

Assemblages that comprise a donor element and a receptor are disclosed. The donor element comprises a binder and particles of a cyanoacrylate polymer. The assemblages can be thermally imaged to form lithographic printing plates.
摘要:
A process amplifies structured resists by utilizing a reaction between a nucleophilic group and an isocyanate group or thiocyanate group to link an amplification agent to a polymer present in the photoresist. The amplification agent includes aromatic and/or cycloaliphatic groups. An isocyanate group or a thiocyanate group and a nucleophilic group form a reaction pair; one of the partners is provided on the polymer and the other partner on the amplification agent. The amplification reaction takes place more rapidly than a linkage to carboxylic anhydride groups. Furthermore, the amplification reaction permits the use of polymers which have high transparency at short wavelengths of less than 200 nm, in particular 157 nm.
