摘要:
The present invention provides a thermal crosslinking accelerator by which etching selectivity with a toplayer resist is improved so that even minutes pattern forms after etching is improved compared to when existing silicon-containing resist underlayer is used. Provided is a thermal crosslinking accelerator of a polysiloxane compound represented by Formula (A-1). R^11, R^12, R^13, and R^14 respectively represent hydrogen atoms, halogen atoms, C1-20 straight-chain, branched, or cyclic alkyl groups and the like, C6-20 substituted or non-substituted aryl groups, or C7-20 aralkyl groups and the like. Partial or overall hydrogen atoms of the groups may be substituted by alkoxy groups and the like. a, b, c, and d are integers of 0-5. When a, b, c, and d are 2 or more, R^11, R^12, R^13, and R^14 may form a cyclic structure. L is lithium and the like.

PURPOSE: A silicon skeleton-containing polymer compound is provided to alleviate a separation problem on a metal wire such as Cu and Al, an electrode, a substrate, or SiN substrate and to form micropatterns in a wide wavelength region. CONSTITUTION: A silicon skeleton-containing polymer compound is a resin including a silicone skeleton having a crosslinkable group or a reaction point deriving a crosslinking reaction, is formed by coupling an isocyanuric acid skeleton with a terminal of the molecule, and has a weight average molecular weight of 3,000-500,000. A resin composition comprises the silicon skeleton-containing polymer compound; a crosslinking agent; a photoacid generator generating acids by being decomposed by a light with a wavelength of 190-500 nm; and a solvent.
