Abstract
A pixel circuit including a transistor, a blocking layer and an output circuit is disclosed. The transistor includes a first doped region and a second doped region disposed on opposite sides of a channel of the transistor proximate to a first surface of a semiconductor substrate such that photo-carriers generated inside the semiconductor substrate in response to incident light flow into one region of the first and second doped regions. The blocking layer is disposed between the other region of the first and second doped regions and a second surface of the semiconductor substrate opposite to the first surface. The blocking layer is configured to block the photo-carriers from flowing into the other region of the first doped region and the second doped region directly. The output circuit outputs an image signal according to a voltage signal outputted from the transistor.
