Patent number: 12222647
Abstract: A photoresist composition includes a conjugated resist additive, a photoactive compound, and a polymer resin. The conjugated resist additive is one or more selected from the group consisting of a polyacetylene, a polythiophene, a polyphenylenevinylene, a polyfluorene, a polypryrrole, a polyphenylene, and a polyaniline. The polyacetylene, polythiophene, polyphenylenevinylene, polyfluorene, polypryrrole, the polyphenylene, and polyaniline includes a substituent selected from the group consisting of an alkyl group, an ether group, an ester group, an alkene group, an aromatic group, an anthracene group, an alcohol group, an amine group, a carboxylic acid group, and an amide group. Another photoresist composition includes a polymer resin having a conjugated moiety and a photoactive compound. The conjugated moiety is one or more selected from the group consisting of a polyacetylene, a polythiophene, a polyphenylenevinylene, a polyfluorene, a polypryrrole, a polyphenylene, and a polyaniline.
