Abstract:
A unit pixel of an image sensor and a photo detector are disclosed. The photo detector of the present invention configured to absorb light can include: a light-absorbing part configured to absorb light by being formed in a floated structure; an oxide film being in contact with one surface of the light-absorbing part; a source being in contact with one side of the other surface of the oxide film and separated from the light-absorbing part with the oxide film therebetween; a drain facing the source so as to be in contact with the other side of the other surface of the oxide film and separated from the light-absorbing part with the oxide film therebetween; and a channel interposed between the source and the drain and configured to form flow of an electric current between the source and the drain.
