Abstract: A linear image sensor using phototransistors as light receiving elements has improved after-image characteristics and reduced production costs by providing a light-receiving MOS diode proximate each photosensor, placing the MOS diode in an inversion state during the accumulation of photo-charge so that the accumulated photo-charge is accumulated at a base region of the phototransistors, placing the MOS diode in an accumulating state during a reset operation to return the phototransistors to an initial state after a readout operation has been performed, so that residual charge without reading out is transferred to the base region of the phototransistors and an after-image caused by residual charge is reduced through an emitter of the phototransistors.

Abstract: A method of inspecting and a method of manufacturing image sensors formed on a surface of a semiconductor wafer. A semiconductor wafer is provided having image sensors formed on its surface. Grooves are cut at boundaries between image sensors to be inspected, so that each groove has a depth that is smaller than the thickness of the semiconductor wafer. The grooves are cut in the boundaries between the image sensors so that photoN sensing carriers generated in the boundary regions, that are not generated by the image sensor being inspected, do not affect the inspection of the image sensor. The characteristics of the image sensors are inspected before cutting through the semiconductor wafer to form individual image sensors. Thus, in accordance with the present invention, the electrical characteristics of the image sensors can be accurately ascertained either before or after separation from the semiconductor wafer.

Abstract: An improved image sensor comprises a plurality of photo-sensing elements each comprising an impurity diffusion layer formed in a surface of a semiconductor substrate and arrayed linearly. The photo-sensing elements are of an opposite conductivity type than that of the semiconductor substrate. A transparent insulating film is formed on the photo-sensing elements and the surface of the semiconductor substrate. A non-light transmitting shading film is formed over the transparent insulating film and has photo-sensing windows which overlay a part of each of the photo-sensing elements. The shape and area of each of the photo-sensing elements is equal. The area of each of the photo-sensing windows is equal, but the shape of the first and last photosensing windows is different from that of the remaining photosensing windows. By this arrangement, the amount of photoexcited carriers generated is uniform at all photo-sensing regions, since the area of all photo-sensing windows is equal. Also, since the area and shape of all photo-sensing elements is the same, the amount of photo-excited carriers stored by all the photo-sensing elements is equal, and thus an output current read out from the elements is uniform.

Abstract: The semiconductor image sensing device is comprised of a single crystal substrate of one conductivity type, formed thereon with an array of photodetector 5 for effecting photo-electric conversion, a read-out circuit for sequentially reading out an output signal from each photodetector, an amplifier for voltage-converting the read output signal, and a voltage regulator for providing a constant voltage. The read-out circuit and the photodetectors are driven by a lower voltage supplied from the integrated voltage regulator so as to reduce a switching noise generated in the read-out circuit. S/N ratio of the semiconductor image sensor is improved by reducing the switching noise. Further, the power consumption can be saved by driving the read-out circuit at the lower voltage.
