ALKALI DEVELOPABLE RESINS AND PHOTOSENSITIVE RESIN COMPOSITION COMPRISING THE SAME

摘要

PURPOSE: An alkali-developable resin and a photosensitive resin composition including the same are provided to remove ball-shape pin holes and improve process margin. CONSTITUTION: An alkali-developable resin comprises recurring unit marked as chemical formula 2 and recurring unit marked as chemical formula 1. Here, R1 indicates hydrogen or C1-6 alkyl group, R2 indicates C3-20 alkyl group. R3 and R4 are identical or different from each other and respectively and independently indicates C3-20 alkylene and a and b are respectively indicate 1-90. The photoresist resin composition material comprises a binder including the alkali soluble resin composition, polymerizable compound including ethylenically unsaturated bond, and a photo initiator and solvent.
