Using patterns in microfiche as photomasks in 10-mu m-scale microfabrication
Microfiche has been used as the photomask in 1:1 contact photolithography to generate structures of photoresist with features as small as 10 mu m. Optical reduction of images that were printed by a high-resolution image setter on transparent polymer sheets generated patterns in microfiche. The photoresist patterns generated using microfiche as the photomask are useful in the fabrication of elastomeric stamps/molds/membranes for soft lithography. Four test structures fabricated using microfiche as photomask and soft lithography are used to evaluate the utility and resolution of this technique.
