Claim:
1. A semiconductor device, comprising: a carrier substrate; a first color filter; a second color filter, wherein a transmission wavelength range of the first color filter is longer than a transmission wavelength range of the second color filter; a first photodetector disposed between the carrier substrate and the first color filter; a second photodetector disposed between the carrier substrate and the second color filter; a plurality of first microstructures disposed between the first color filter and the carrier substrate and adjacent to the first photodetector for enhancing intensity of light incident on the first photodetector, wherein the first microstructures are present on a surface of the first photodetector; and a dielectric layer disposed between the second color filter and the carrier substrate and having a substantially flat surface in contact with the second photodetector, wherein the dielectric layer and the first microstructures are integrally formed.
