Phenolic dyes as nonbleachable absorbers compatible with novolac resins for linewidth control in photoresists

Patent ·
OSTI ID:6086684
Photoresist techniques and compositions are provided employing curcumin as an absorptive dye for the purpose of reducing linewidth non-uniformity caused by scattered and reflective light from the substrate-resist interface. The photoresist compositions containing curcumin as the absorptive dye are used in the production of microelectronic circuitry by both single layer and multilayer photoresist techniques.
