Microfluidic Biochip

SU-8 MoldThis is a scanning electron microscope (SEM) image of a microfluidic biochip on a fused silica substrate. The image shows the nickel hard mask used during dry etching.

Equipment used:

  • E-beam 1 evaporator to deposit a seed layer on the fused silica substrate.
  • Laurell Spinner to spin photoresist.
  • KS MA6 Mask Aligner to UV expose and pattern the fused silica substrate.
  • Electroplating station to plate the nickel hard mask.
  • SPTS Glass Etcher to dry etch the microfluidic channels.
  • Dektak XT or Dektak 3 profilometers to measure channel’s etch depth.
  • Optical microscope to inspect the completed biochip.
