  • Plastic microelectromechanical systems (PMEMS) process has been developed for microfluidics and bioMEMS applications. The fabrication process mainly uses parylene to form channels and SU-8 to planarize the surface for external tube coupling. This process is a low temperature process (maximum temperature of 90 °C) and can use any substrate including plastic, glass and silicon. Therefore, it is CMOS compatible and can be used to integrate microfluidics with CMOS. Furthermore, by using plastic substrates, cheap and disposable microfluidic devices can be fabricated.
  • Parylene can also be used as a mechanical material to fabricate surface micromachined beams, diaphragms and cantilevers for applications that require low Young’s modulus. Therefore, parylene technology can be used as a platform to integrate CMOS and electrodes, heaters, microchannels, cantilevers, beams and diaphragms.
  • Deadlines for the next run:
