• AppNano micro-fabricates thin membranes made of Silicon, Silicon Oxide, and Silicon Nitride
  • Membranes can be coated with optional materials for functionalization
  • Further customization is possible on the chip size, window size, thickness of the membrane
Membranes- Si/SiO/SiN
Membranes- Top view
Membranes- Side view
Silicon Window (SIWD)
  • SIWD are useful for electrical conductance studies
  • Membranes can easily be functionalized to hydrophobic or hydrophilic surface to suit different applications
Nitride Window (NIWD)
  • NIWD membranes are made with low stress silicon nitride
  • Membranes can be coated with optional materials to suit specific needs
Oxide Window (OXWD)
  • OXWD membranes are electrically insulating with a hydrophilic surface
  • These membranes can be coated with optional materials according to customer request
