| Abstract: | We show proof of concept of a real-time reconfigurable photomask fabricated from holographically
formed polymer-dispersed liquid crystal !H-PDLC" reflection gratings on etched indium tin oxide
patterned electrodes. H-PDLC films were formed using a thiolene based polymer to have a reflection
wavelength that modulates 440 nm, the peak sensitivity wavelength of Shipley 1800 series positive
photoresist. A working prototype of this adaptable photomask device is shown by comparing
patterns formed using the H-PDLC mask and similar patterns formed using a static contact
photomask showing that H-PDLC films have the ability to modulate 440 nm light and control the
exposure dose of photoresist. |
