A 1/2.3-inch 10.3Mpixel 50frame/s Back-Illuminated CMOS Image Sensor

📋 论文概要

本文提出了一款1/2.3英寸10.3百万像素背照式CMOS图像传感器，支持50帧/秒的帧率，面向数码相机和高清摄像机应用。它通过背照式技术解决了传统前照式传感器灵敏度低、饱和信号小的问题，实现了高像素、高灵敏度、高饱和信号和低噪声。

💡 主要创新点

• 采用背照式像素结构，将光电二极管置于电路层上方，提高了量子效率和灵敏度。
• 实现了10.3百万像素的高分辨率与50帧/秒的高速读出，平衡了像素数和帧率。
• 优化了像素设计和工艺，在1/2.3英寸小尺寸下获得高饱和信号和低噪声性能。

These applications require high-pixel-count, high-sensitivity, high saturation signal, low noise and high-speed imaging for image quality [1]. The sensor is scaled down to get a higher resolution due to higher pixel count. Several approaches such as a Cu process to reduce the pixel height and inner micro-lenses to gather rays of incident light have been proposed to overcome electro-optical challenges [2-4]. The BI process has been reported as one of the
