Radiation-sensitive polymers have found wide use in minacroelectronic fabrication processes as resists. Poly (methyl methacrylate), PMMA, the most widely used E-beam and UV resist, possesses a number of desirable process characteristics, but lacks sensitivity sufficient to allow high production throughput. We have found that a structural modification of PMMA involving incorporation of a trifluoromethyl group results in a significant increase in sensitivity.
