Photometry TRIZ Cases
- SPAD Pixel Trench Structure for Higher Quantum Efficiency
An in-pixel trench, hole accumulation layer, and pinning layer cut hole current resistance while extending optical path length in a ToF SPAD pixel.
- Phononic Crystal Thermal Insulator Layout for Crack-Resistant IR Sensors
Segmented phononic crystal domains with solid regions cut crack growth while preserving conductivity and thermal insulation in infrared sensors.
- SPAD TOF Quenching Control for Accurate Distance Sensing
Dynamic quenching voltage control tunes SPAD sensitivity from photon counts, improving TOF distance accuracy across varying signal conditions.
