| 摘要 |
The present invention relates to an image sensor having an improved spectral characteristic. The present invention can implement an image sensor having a substrate-stacking structure including two substrates, each of which has a photodiode disposed therein, and generate a color signal having an improved spectral characteristic on the basis of an electrical signal output from the photodiode included in each of the two substrates, thereby improving the color characteristic and sensitivity of the image sensor. |
