0.8μm-pitch CMOS Image Sensor with Dual Conversion Gain Pixel for Mobile Applications

The paper introduces a 0.8μm-pitch CMOS Image Sensor (CIS) with Dual Conversion Gain (DCG) pixel technology. The 0.8μm-pitch has been developed to decrease the pixel size with the demand of higher resolution from the mobile CIS market. However, for the 0.8μm-pitch, it is crucial to overcome the degradation of Full Well Capacity (FWC) as well as Signal-Noise Ratio (SNR) performance due to shrink in pixel size, and the DCG pixel technology can be a way to resolve this problem. We expect that the DCG pixel technology will be an effective solution and contribute to expanding high resolution in the mobile CIS market.
