Abstract :
Au deposited SU-8 microdots comprised SU-8-PET microchip using low temperature polymer bonding technology is developed. A fine microdot array (1μm×1μm×0.5μm dots with 2μm pitch in area of 50μm×5mm) is fabricated by electron beam lithography (EBL) using SU-8 as a negative tone resist. A microchannel structure is formed with UV patterned SU-8 on a glass substrate. The SU-8 structure is sealed with a PET film by low temperature silane coupling bonding (140oC, 1.5MPa, 5min). The proposed microchip is fabricated successfully without leakage and is applicable as a microchip electrophoresis.
