According to one embodiment, a pattern forming material is disclosed. The pattern forming material contains a polymer. The polymer includes a specific first monomer unit. The monomer unit has a structure having ester of a carboxyl group at a terminal of a side chain. In the ester, a carbon atom bonded to an oxygen atom next to a carbonyl group is a primary carbon, a secondary carbon or a tertiary carbon. The pattern forming material is used for manufacturing a composite film as a mask pattern for processing a target film on a substrate. The composite film is formed by a process including, forming an organic film on the target film with the pattern forming material, patterning the organic film, and forming the composite film by infiltering a metal compound into the patterned organic film.

The invention relates to an one pack ambient cure crosslinkable modified vinyl branched ester polymer with vinyl silane and a water scavanger. The copolymer composition can be formulated to the desired viscosity that allows the application by standard technics, and the curing is optimized in the presence of an appropriated catalyst as one pack system to be cure at room temperature.
