Uniform Fabrication of Moems Arrays Using Dry Thick Resist Films
Résumé
This study aims at focusing a laser beam at the center of a microfluidic channel for optical bio-sensing applications thanks to the collective integration of tunable microlens arrays on VCSELs devices. High aspect-ratio polymer-based MOEMS are successfully fabricated on small-sized
samples using thick dry photoresist films. Such dry films are easier to use and less expensive than standard thick SU-8 and can be efficiently stacked on fragile GaAs samples using a soft-thermal-printing technique. By combining double UV exposure and planar metallization, uniform fabrication of MOEMS arrays is enabled and fabricated devices exhibit reproducible electro-thermal behavior.
