Next generation shadow masks

Shadow mask lithography is used in a variety of microsystem applications to realize a cost effective, structured thin film deposition. Especially in the field of OLED displays and sensors for point-of-care diagnostics shadow masks are considered to be the mainstream technology. Fine Glass Masks are a superior technology to the Fine Metal Mask used today.

Fine Metal Mask

Today's shadow masks are mainly made of metal. Fine Metal Mask are characterized by a number of disadvantages.

  • Limited resolution
  • Warpage
  • Undercut profile due to the manufacturing process
  • Unfavourable thermal behaviour

Fine Glass Mask

Using our unique LIDE technology, Fine Glass Mask with superior properties can be produced.

  • Ultra high density masks with sharp features
  • Formation of wrinkles impossible
  • Reduced shadowing effect
  • Thermal expansion identical to typical substrates such as glass and silicon
  • Glass is chemically resistant
    Cleaning with aggressive chemistry becomes possible
