PHOTO DETECTOR AND METHOD FOR FABRICATING THE SAME

摘要

A photo detector and a method for fabricating the same are provided. The photo detector includes a first substrate and a photo conversion element. The first substrate has a sensor element array for receiving a light with a spectrum in a specific wavelength range. The photo conversion element is disposed on the sensor element array, where the photo conversion element includes a photo conversion material layer and a doped photo conversion material column structure layer. A luminescent spectrum of the doped photo conversion material layer column structure layer is overlapped with the spectrum in a specific wavelength range, and a luminescent spectrum of the photo conversion material layer is non-overlapped with the spectrum in a specific wavelength range.
