    摘要： An image sensor may include a first photo-sensing device on a semiconductor substrate and configured to sense light of a first wavelength spectrum, and second and third photo-sensing devices integrated in the semiconductor substrate and configured to sense light of a second and third wavelength spectrum, respectively. The first photo-sensing device may overlap each of the second and third photo-sensing devices in a thickness direction of the semiconductor substrate. The second and third photo-sensing devices do not overlap in the thickness direction and each have an upper surface, a lower surface, and a doped region therebetween. The third photo-sensing device includes an upper surface deeper further from the upper surface of the semiconductor substrate than the upper surface of the second photo-sensing device and a doped region thicker than the doped region of the second photo-sensing device. The image sensor may omit the first photo-sensing device.

    摘要： A sensor includes a first electrode and a second electrode, and a photo-active layer between the first electrode and the second electrode. The photo-active layer includes a light absorbing semiconductor configured to form a Schottky junction with the first electrode. The photo-active layer has a charge carrier trapping site configured to capture photo-generated charge carriers generated based on the light absorbing semiconductor absorbing incident light that enters at least the photo-active layer at a position adjacent to the first electrode. The sensor is configured to have an external quantum efficiency (EQE) that is adjusted based on a voltage bias being applied between the first electrode and the second electrode.
