Abstract: A pixel of a distance sensor includes a photosensor that generates photocharges corresponding to light incident in a first direction. The photosensor includes a plurality of first layers having a cross-sectional area increasing along the first direction after a first depth and at least one transfer gate which receives a transfer control signal for transferring the photocharges to a floating diffusion node. A strong electric field is formed in the direction in which the photocharges move horizontally or vertically in the pixel, thereby accelerating the photocharges, allowing for increased sensitivity and demodulation contrast.

Abstract translation: 距离传感器的像素包括产生对应于沿第一方向入射的光的光电荷的光传感器。 光传感器包括多个第一层，其具有沿着第一深度之后的第一方向的横截面积增加的多个第一层和接收用于将光电荷转移到浮动扩散节点的转移控制信号的至少一个传输门。 在光电荷在像素中水平或垂直移动的方向上形成强电场，从而加速光电荷，允许增加灵敏度和解调对比度。
