PURPOSE:To simplify a manufacturing process, to eliminate defects due to pinholes, and to obtain a photosensor which is high in sensitivity and low in afterimage by a method wherein an electrode of a certain conductivity layer is led out through the intermediary of an i layer. CONSTITUTION:A p-type layer 34, and i layer 33, and an n-type layer 31 are laminated to form a PIN vertical type photosensor, and an electrode 32 of one conductivity type layer 34 is led out through the intermediary of the i layer 33. That is, the electrode 32 is formed on the opposite side to the conductivity type layer 34 sandwiching the i layer 33 in between them and in line with the other conductivity type layer (serving also as n electrode) 31. And, the electrode 32 is formed on the opposite side to the conductivity type layer 34 sandwiching the i layer in between them, so that the i layer 33 and the conductivity type layer 34 can be continuously grown. By this setup, a photo sensor of this design can be made high in sensitivity, small in afterimage, and free from defects due to pinholes, and simplified in a manufacturing process.

Since the thickness b of one layer (7) between the type layer (8) and the n-type layer (6) can be made thin (for example, b=1 μm), there is an advantage that the electric field is strong and the afterimage is small. However, on the other hand, for example, when forming an Aβ electrode for contact on the p-type layer (8), pinhole defects may occur, such as a short circuit between the Aβ electrode and layer 1 (7) due to a pinhole in the p-type layer (8). There will be more. In addition, it is difficult to form this Aβ electrode, for example, after growing one layer (7) and paqueuning it, the p-type layer (
8), and Aβ is formed on the p-type layer in the region not corresponding to the first layer.
This had the disadvantage that the manufacturing process, such as forming electrodes, was complicated.
