A back side illumination (BSI) image sensor includes at least one pixel. The pixel area includes a photo diode and a transfer transistor. The transfer transistor has a control electrode made of a gate poly and a gate oxide for receiving a control instruction, a first electrode coupled to the photo diode, and a second electrode, wherein an induced conduction channel of the transfer transistor partially surrounds a recessed space which is filled with the gate poly and the gate oxide of the transfer transistor.
