Title:
RESIN COMPOSITION, PROCESS FOR PRODUCING RESIN COMPOSITION, AND METHOD OF FORMING RESIN FILM
Document Type and Number:
WIPO Patent Application WO/2002/088845
Kind Code:
A1
Abstract:
A resin composition which comprises a polyimide precursor and a photosensitizer, wherein the polyimide precursor has structural units represented by the following formula (1), wherein A?1¿ is a tetravalent organic group and A?2¿ is a divalent organic group having an alicyclic structure. Due to this polyimide precursor, the composition gives a film having excellent light-transmitting properties in a wide wavelength range. The polyimide precursor has been partly imidized to a degree of 7.5% to 36%. Because of this, the resin composition has low solubility in a developing solution and the unexposed areas do not dissolve in the developing solution. (1)
