Wafer-Level Patternable Light Absorbing Coatings

 

Light absorbing coatings on wafers of almost any material have excellent coverage of the entire surface including edges. Typical coating thickness is from 0.8 to 2 microns with working temperatures from -269 to +350 degrees C.

 

Key features of black optical coatings include:

• Very low reflectivity coatings
• Tailorable electrical resistivity - conductor or insulator
• Etching or lift-off technology
• 3 micron feature size
• Virtually any substrate material - silicon, glass, ceramic, etc.
• No particulation
• Compatibility with lithographic process chemicals
• Vacuum, cryogenic and clean room compatible
