7 Organic resists and external filters Each filtering function requires both On-chip organic resists Interference filters on external glass substrate RGB or Ambient Light Sensing (ALS) IR-pass For multiple filters, patterned external filter is required
8 Fully on-chip filters IMEC XFab - All-dielectric Fabry-Perot: staircase - Multiple masks, partial etching - Thick stack > 1µm - Limited spectral range: R & NIR - Very high transmission and rejection - All-dielectric Fabry-Perot: nanostructured - One mask - Thick stack > 1µm - Limited spectral range: R & NIR - Very high transmission and rejection Glasgow Univ. - Metallic nanostructured filters (plasmonic) - One mask - Thin: typ 0,15µm - Limited spectral range: e.g. visible - Low transmission and rejection
