Abstract
The present disclosure relates to an image sensor structure and a manufacturing method thereof. A detection structure layer and a blind pixel structure layer are used. The detection structure layer and the blind pixel structure layer are effectively combined and further formed by ion implantation. Thus, the space ratio of a single pixel is reduced, the integration and device sensitivity are improved, and the blind pixel array and the pixel array are also in the same environment, thereby further improving the detection sensitivity and reducing the detection error.
