Abstract
Microstructures are fabricated by impinging a radiation beam, such as a laser beam, through a substrate that is transparent to the laser beam, into a negative photoresist layer on the substrate. The negative photoresist layer may be subsequently developed to provide a master for optical and/or mechanical microstructures. Related systems, microstructure products and microstructure masters also are disclosed.
