Advances In 3D CMOS Image Sensors Optical Modeling: Combining Realistic Morphologies With FDTD

In CMOS image sensors, here’s a way to find how device morphology and optical performance are linked.


This paper describes an innovative methodology to investigate the relationship between device morphology and the optical performance of CMOS image sensors. By coupling a FDTD-based 3D Maxwell solver with silicon-accurate process modeling software, we have been able to analyze the sensitivity of image sensor quantum efficiency with respect to statistical variations in nm-scale device topology. Additionally, we studied pyramidal silicon structuration for quantum efficiency enhancement as proposed in [1].
