Electromagnetic Simulation of Image Sensors: From Design to Manufacturability
Over the past decade, CMOS image sensors have grown to a multi-billion dollar market, and are now a fundamental component in mobile phones, digital, web and video cameras, industrial sensors, etc. The push to increase pixel density has resulted in modern pixel designs that are diffraction limited, demanding the rigorous solution of the Maxwell equations to simulate the transmission of the light through the lens, filters before absorption by the photodiode. This webcast discusses the application of TCAD Sentaurus Device EMW to the electromagnetic simulation of CMOS image sensors (CIS) and charge-coupling devices (CCD). Recent improvements to the FDTD algorithm are shown which significantly improve the speed of these simulations, allowing image sensor designers to make more efficient use of TCAD tools throughout the entire design cycle, from conceptual to manufacturability studies.
