Title:
METHOD FOR PRODUCING STRIPPING FILM FOR PRODUCING THIN FILM, METHOD FOR PRODUCING THIN FILM FOR ELECTRONIC COMPONENT, AND STRIPPING FILM FOR PRODUCING THIN FILM
Document Type and Number:
WIPO Patent Application WO/2002/064338
Kind Code:
A1
Abstract:
A method for producing a stripping film (1) for producing a thin film for electronic component by coating a base film (2) with coating liquid (3a) containing silicone resin, drying the coating liquid (3a) to form a stripping layer (3) of silicone resin on the base film (2) and then winding the base film (2), on which the stripping layer (3) is formed, into a roll, wherein the base film (2) is wound while applying a tension in the range of 3-17 N per 100 mm width of the base film (2) on which the stripping layer (3) is formed when the thickness of the base film (2) is in the range of 5-30 $g(m)m. Flatness on the surface of the stripping layer (3) can be ensured while preventing the winding state from ravel or the base film (2) from stretching.
