Optical Window

Anti-reflective coating (ARC) layer to prevent reflection and interference losses

Material on top of Photo Diode reduces transmission
Thickness cannot be defined

Etching to remove material on top of Photo Diode

Applying ARC layer with defined thickness
Reflection loss reduced for dedicated wavelengths
