METHOD OF PREPARING A PATTERNED FILM WITH A DEVELOPING SOLVENT |
摘要 |
A method of preparing a patterned film on a substrate includes applying a silicone composition onto a substrate to form a film of the silicone composition. A portion of the film is exposed to radiation to produce a partially exposed film having an exposed region and a non-exposed region. The partially exposed film is heated for a sufficient amount of time and at a sufficient temperature to substantially insolubilize the exposed region in a developing solvent that includes a siloxane component. The non-exposed region of the partially exposed film is removed with the developing solvent to reveal a film-free region on the substrate and to form the patterned film including the exposed region that remains on the substrate. The film-free regions is substantially free of residual silicone due to the presence of the siloxane component in the developing solvent. |
