摘要:
The invention relates to an antireflective coating composition comprising a crosslinker and a crosslinkable polymer capable of being crosslinked by the crosslinker, where the crosslinkable polymer comprises a unit represented by structure (1): [-A-B-C-] (1) where A is a fused aromatic ring, B has a structure (2), and C is a hydroxybiphenyl of structure (3) where R1 is C1-C4alkyl and R2 is C1-C4alkyl.The invention further relates to a process for forming an image using the composition.
摘要:
Disclosed herein is a formulation for depositing a cured underlayer for promoting the formation of self assembled structures. The underlayer comprises: (a) a polymer comprising at least one pendant vinyl ether monomer repeat unit having the structure, (I): wherein R is chosen from H, C1-C4 alkyl, or halogen, and W is a divalent group chosen from C1-C6 alkylene, C6-C20 arylene, benzylene, or C2-C20 alkyleneoxyalkylene; (ii) optional thermal acid generator; and (c) a solvent. The invention also relates to processes of forming a pattern using the underlayer.
