Semiconductor Wafer Microlithography
Torrent Photonics provides semiconductor wafer microlithography as part of its comprehensive semiconductor sensor supply chain. Capabilities include active wafer deposition, color resists on wafer and dichroic coatings patterned on wafer, with support for customer-supplied material up to 8 inches.
Active Wafer Deposition:
- Improved S/N on ambient light, proximity & biometric sensors
Color Resists on Wafer:
- Wafer planarization for pattern resolution on drastic topography
- RGB-CYM filter spectral performance
- UV cure and low heat options
Dichroic Coatings Patterned on Wafer:
- NIR, VIS, and UV filter performance
- Minimal dark current contamination in process
