图像传感器及用于形成图像传感器的方法
摘要：
本公开涉及图像传感器及用于形成图像传感器的方法，其中一种图像传感器包括：衬底，所述衬底中形成有光电二极管；以及聚光部，所述聚光部位于所述衬底上，其中，所述聚光部具有斜面，且所述聚光部被构造为：使得要进入所述光电二极管的周围区域的光从所述斜面进入所述聚光部，并将所述光向所述光电二极管的方向折射。本公开涉及的图像传感器及用于形成图像传感器的方法，使得更多的光进入衬底中的光电二极管的区域，从而改善图像传感器的光敏感度。
摘要（英）：

The invention relates to an image sensor and a method for forming the image sensor. The image sensor comprises a substrate and a light collecting part, wherein a photodiode is formed in the substrate;the light collecting part is arranged on the substrate, and the light collecting part is provided with an inclined surface; the light collecting part is constructed so that light entering the surrounding area of the photodiode can enter the light collecting part from the inclined surface and the light can be refracted in the direction of the photodiode. The invention relates to the image sensor and the method for forming the image sensor, so that more light enters the area of the photodiode in the substrate, and the light sensitivity of the image sensor is improved.
