  • Photoresist formulation
    Patent number: 11815812
    Abstract: A planarization layer and method therefor. The planarization layer has a thickness ranging from about 2 to about 3 microns, and contains from about 8.0 to about 8.5 wt. % photoacid generator; from about 2 to about 3.6 wt. % photoinitiator; from about 0.35 to about 0.5 wt. % green dye; from about 35 to about 46 wt. % multifunctional epoxy compound; from about 35 to about 50 wt. % of one or more difunctional epoxy compounds; and from about 1 to about 2.6 wt. % silane adhesion promoter, wherein all weight percent is based on a total weight of the layer devoid of solvent.
