摘要： 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.

摘要： 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.

摘要： A voltage at an output terminal of a photodiode is reset to a fixed voltage and an output signal of the photodiode and a dummy signal matching a dark output signal is output by a dummy photodiode comprising an identical component as that of the photodiode. The voltage difference between an input side and an output side of an amplifier is made to match the difference between a reset voltage of the photodiode and a reset voltage of a common signal line and a reset voltage of an output terminal to optimize the size of a MOS transistor forming the amplifier. The offset voltage is set to a constant which does not depend on the size of the MOS transistor. The amplifier is formed with CMOS devices and is selectively operated only during an output operation to suppress the current consumption.
