Abstract: The present invention relates to a vertically-charge-transferring pixel sensor (VPS) and methods of manufacture and operation thereof. In the VPS, deep trench isolation (DTI) structures and shallow trench isolation (STI) structures in a substrate contain deep trench electrodes and shallow trench electrodes, respectively. In a light sensing operation, a positive bias voltage can be applied between the substrate and the deep and shallow trench electrodes to raise a potential barrier at boundaries of the DTI and STI structures and the substrate. This reduces the likelihood of photoelectrons being captured at the boundaries, thus reducing loss of photoelectrons and contributing to enhanced quantum efficiency. In addition, in the STI structures, the shallow trench electrodes may be offset toward light sensing regions beside the STI structures.
