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 linear image sensor IC comprising a plurality of switching circuits each connected to a plurality of light receiving elements in series; scanning circuits for sequentially switching said switching circuits; and driving circuits for operating said scanning circuits, wherein a LOCOS isolation layer is formed between an edge in the main scanning direction of the linear image sensor IC which is closest to an array of the light receiving elements and a light receiving portion of the light receiving element. The inventive image sensor IC is mounted by devising so that the circuit can be put into a thin and long pattern in the scanning direction, so that the chip having a width thinner than a thickness thereof which had been beyond expectation by the prior art can be realized. The use of this very thin IC allows a compact IC assembling substrate having less fluctuation among ICs to be manufactured at low cost. Even more, it becomes possible to mount ICs readily on a cylindrical substrate which had been also difficult in the past. Thereby, electronic devices such as a compact and low cost multi-chip type image sensor or multi-chip type thermal head can be realized. Accordingly, it becomes possible to bring down the cost thereof, which had been difficult in the past, and to realize a low cost facsimile.

摘要： To eliminate a residual image due to residual charge in an image sensor circuit and provide an effective bright-time output, the image sensor is provided with a reset switch connected to a photodiode. After the potential of the photodiode is held through a first amplifier in two holding circuits as an image signal and an initial signal, the initial signal and the image signal are sequentially output through a second amplifier. By resetting the photodiode to a desired potential to produce an initial signal, a residual image can be eliminated.

摘要： A light receiving element is provided with a phototransistor and a light receiving MOS diode proximate thereto and having a gate electrode covering a portion of the base region of the phototransistor. The gate electrode permits transmission of a portion of received light. The light receiving MOS diode forms an inversion layer in a substrate adjacent the base of a phototransistor during the time photo charges are stored, and generated photo charges are stored in the inversion region and the base region of the phototransistor. During the storage state, the potential of the inversion region and the base region of the phototransistor is limited, so that the intensity of an electric field applied to an insulating film between the electrode and the semiconductor substrate is 0.7 MV/cm or less. Alternatively, the potential of the electrode in a waiting state is fixed or made floating, so that an electric field is not applied, and recombination at the surface of the semiconductor substrate is made stable.

摘要： A scanning circuit has path switches connected between a plurality of data flip-flop circuits of the scanning circuit for sequentially reading an output signal in synchronism with a clock. A plurality of control signal lines select the path switches to arbitrarily skip reading of the flip-flop circuits that do not require the scanning circuit and always fix a potential of the skipped data flip-flop circuit. Only the arbitrary data is read, and in the case where unnecessary data exists, reading is skipped, to thereby increase the read rate.
