摘要： PROBLEM TO BE SOLVED: To enable correction of the offset output value without independently arranging photoelectric conversion elements by arranging the shielding member, whose X-ray transmittance is 0% at the incident side of the X rays or light of the photoelectric conversion element in correspondence with an arbitrary photoelectric conversion element. SOLUTION: A photoelectric conversion device divides the total of 9 pixels into 3 blocks and transfers the outputs of 3 pixels per 1 block at the same time. The signal is sequentially converted into the output by a detecting integrated circuit IC through this signal wiring SIG and outputted. Furthermore, the 3 pixels in 1 block are arranged in a lateral direction, and blocks are sequentially arranged longitudinally. Thus, the respective pixels are arranged in two dimensions. A shielding member 70, whose X-ray transmittance or light transmittance is about 0%, is arranged on the incident side of the X-rays or the light of a photoelectric conversion element S13, in correspondence with the arbitrary photoelectric conversion element S13 of the photoelectric conversion device having respective photoelectric conversion elements S11-S33 of respective pixels arranged in two dimensions.

摘要： PROBLEM TO BE SOLVED: To improve yield and reduce cost by arranging and bonding a plurality of substrates on which two-dimensionally arrayed photoelectric conversion elements are mounted in such a manner that the photoelectric conversion elements are flatly adjacent to one another. SOLUTION: Four photoelectric conversion devices 100, 200, 300 and 400 of perfectly the same structure are bonded with the smallest possible gaps between one another, thus constituting one photoelectric conversion device having a large area. In this case, the photoelectric conversion devices are rotated by 90 deg. with respect to one another. At the large area photoelectric conversion device is constituted by bonding the four photoelectric conversion devices 100 to 400 without having gaps, the yield of each of the photoelectric conversion devices is raised. In addition, through scanning circuits SR1-1 to SR1-10 and detection circuit IC-1 to IC-10 are provided on each of the four sides of the photoelectric conversion device having a large area, one type of IC chip each suffices to constitute a drive circuit of the photoelectric conversion device, and the cost of the driving circuit is not increased.

摘要： PROBLEM TO BE SOLVED: To easily manufacture a photoelectric transducer of low cost whose SN ratio is high, and stabilize the characteristics, by arranging an insulating layer which blocks the passage of positive and negative carriers, setting an injection block layer in one position, and making a structure provided with storage function and switch function is the photoelectric transducer. SOLUTION: When light is made to enter an i layer 4, the light is absorbed and electron-hole pairs are generated. The electrons are guided to a D electrode 6 by an electric field, and the holes move in the i layer 4 and reach the interface of the i layer 4 and an insulating layer 7. The holes can not move in the insulating layer 7 so that the holes remain in the i layer 4. At this time, since the electrons transfer to the D electrode 6 and the holes transfer to the insulating layer 7 interface in the i layer 4, a current flows from a G electrode 2. The current corresponds to the electron-hole pairs generated by the light and so is in proportion to the incident light.

摘要： PROBLEM TO BE SOLVED: To make it possible to recognize each picture element simply and quickly by giving a code for prescribing the location of the picture element on or below wiring for a switch element or a photoelectric converting element at the position corresponding to the picture element. SOLUTION: A code 53 prescribing the position of a picture element 200 is formed on or below wiring of a switching element or a photoelectric converting element at the position corresponding to the picture element 200 in a panel by a semiconductor layer on a common control wiring 1. Also, a semiconductor layer for forming this code 53 is formed with a semiconductor layer the same as the intrinsic semiconductor layer 33 of the TFT portion 3 and is formed simultaneously in the process forming the intrinsic semiconductor layer 33 of the TFT portion 3. By doing this, each picture element 200 can be recognized simply and quickly and efficiency and yield in the production process of the semiconductor device can be enhanced without creating any decrease in numerical aperture or worsening of rated functions.
