| Popis: | A 1280×960 floating diffusion storage global shutter image sensor is implemented in a 3D stacked back illuminated indirect time of flight sensor (iToF). The sensor, achieves 18,000e- full well capacity and 32% quantum efficiency (QE) with a pyramid surface for diffraction (PSD) structure [1], utilizing a 3.5µm pixel. Low power consumption is also achieved, due to low leakage current for the iToF pixel and low resistance Cu-Cu connection metal wiring. These device architectures enable high resolution and wide dynamic range 3D depth sensing for both near and far objects. |
