Fine Glass Mask

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
