Abstract

We report on reversible deformation in photoresist structures patterned using femtosecond direct laser write technique. Significant swelling and shrinkage of exposed features by up to 10% in negative-tone hybrid organicinorganic Zr containing photoresist SZ2080 were found to occur during wet development and rinse following the laser processing. Amount of swelling and shrinkage is controllable within 10% margin via use of different rinse agents and the shrinkage-swelling cycle can be repeated many times. Simple interpretation of this phenomenon is presented, and several potential application areas in diffractive optics, micro mechanics, actuation, and environmental sensing are outlined.
