Abstract
An image-sensing device is provided. The image-sensing device includes a substrate, a light-sensing element, a first dielectric layer, a light-guiding structure, and a patterned conductive layer. The light-sensing element is disposed in the substrate. The first dielectric layer is disposed on the first side of the substrate. The light-guiding structure is disposed in the first dielectric layer. The patterned conductive layer is disposed between the light-sensing element and the light-guiding structure. In addition, the patterned conductive layer includes a subwavelength structure. An image-sensing system including the above image-sensing device is also provided.
