Fabrication of plastic microchips by hot embossing.


Plastic microchips with microchannels (100 microm wide, 40 microm deep) of varying designs have been fabricated in polymethylmethacrylate by a hot embossing process using an electroform tool produced starting with silicon chip masters. Hot-embossed chips were capped with a polymethylmethacrylate top using a proprietary solvent bonding process. Holes were… (More)
