に夫々信号が出力さnる。It is already known in the art that monocrystalline silicon is used in the photoactive layer. As shown in FIG. 1, its basic structure is to provide a plurality of photodiode regions +21, 13), 14) on the surface of a single crystal silicon substrate (1), and to apply different color filters on each of these regions, e.g. Red filter (
5), green filter (6) and blue filter 171t-
In such a sensor, when a visible source enters the substrate 111 through each filter, the infrared cut filter (8) is placed on top of the infrared cut filter (8). , If the n is red, it is placed in the diode area 12I, if it is the edge, it is placed in the diode area 13), and if it is written, it is placed in the diode area 141.
A signal is output to each.

である。Therefore, when single-crystal silicon is used for the photoactive layer, simply passing the red filter through the photodiode region 12+r
i. The infrared radiation in the conventional color sensor described above cannot detect positive 4M color information because the monocrystalline silicon itself is sensitive to the infrared radiation that is attenuated but also incident (strongly depending on the 41 nature). The cut filter 181 is provided to remove such incident infrared sources, and is indispensable.

す。However, the presence of such an infrared cut filter not only complicates the sensor configuration, but also reduces the manufacturing process.
This method has the disadvantage that the process of superimposing the filter on the silicon substrate tends to damage the fragile silicon substrate.

When it is red, it enters the first sensing element (12R)K through the red filter 11K (13R) and the substrate Ut, and generates free carriers at xllm (15b) in the cough element. These free carriers are collected at the first and second electrodes I, and a voltage is generated between the two electrodes.

傷めることもない。As shown by curve B in Figure 1!2, the sensitivity characteristic of an amorphous semiconductor has a band that mostly falls within the visible light region. For this reason, with the non-implemented separate color sensor, even if infrared light enters through the red filter film (13R), it is hardly detected, and therefore an infrared cut filter, which is conventionally required, is not used. Accurate color information can be detected without using . In addition, the color sensor of this embodiment [1 (for IK, each color filter (13R), (1
, 5G), and (13B) are attached to the surface of the substrate opposite to the active emulator, so that they will not damage the original active layer 051 during leisure.
