POSITIVE TYPED PHOTOSENSITIVE COMPOSITION COMPRISING NOVLE POLYAMIDE DERIVATIVES

摘要

PURPOSE: A positive type photo-sensitive resin composition containing a polyamide derivative is provided to reduce the loss of a non-exposed part after development and to improve thermal stability. CONSTITUTION: A positive type photo-sensitive resin composition includes a polyamide derivative represented by chemical formula 1. In chemical formula 1, R1, R2, R4, and R5 are respectively divalent to hexavalent acyl groups with two or more carbon atoms; R3 is a hydrogen atom or a C1-10 alkyl group; k is the integer of 10 to 1000; l is the integer of 1 to 1000; n and m are respectively the integer of 0 to 2; the sum of n and m is more than 0; and X is a C2-30 carboxylic group.
