LIGHT DETECTING DEVICE |
| 摘要 |
A light detecting device is provided, comprising a substrate having a patterned metal layer formed thereon; a dielectric layer formed on the substrate, first pixel element formed on the dielectric layer, and a second pixel element. The dielectric layer at least has a first trench, and the first trench is positioned below the level of the first pixel element. The second pixel element comprises a buried portion formed correspondingly to the first trench, and an upper portion formed on the buried portion. The upper portion of the second pixel element is positioned at the same level of the first pixel element. |
