IMAGE SENSOR DEVICE AND METHOD FOR FORMING THE SAME |
| 摘要 |
Embodiments of the disclosure provide an image sensor device. The image sensor device includes a semiconductor substrate including a front surface, a back surface opposite to the front surface, a light-sensing region close to the front surface, and a trench adjacent to the light-sensing region. The image sensor device includes a light-blocking structure positioned in the trench to absorb or reflect incident light. |
