Abstract
The present invention relates to a structure of an photosensor structure having improved optical properties by including a copper halide region, and a method of manufacturing the same. The photosensor structure includes a silicon semiconductor substrate and junctions formed in the silicon semiconductor substrate and having regions of at least three opposite polarities. The junctions may be arranged substantially vertically aligned with each other, and at least one of the junctions may be a junction of a copper halide region of a first polarity and a silicon region of a second polarity. Accordingly, the quantum efficiency is improved by the optical characteristics of the copper halide, and the effect of reducing the size of the manufactured photosensor can be obtained.
