摘要： A radiation detector of this invention has a barrier layer on the upper surface of a high resistance film along the outer edge of a common electrode, which enables prevention of a chemical reaction between an amorphous semiconductor layer and a curable synthetic resin. The barrier layer is adhesive to the curable synthetic resin film, and this can prevent strength being insufficient, such that temperature changes cause separation in interfaces between the barrier layer and curable synthetic resin film, thereby reducing the effect of inhibiting warpage and cracking. The material for the barrier layer is an insulating material not including a substance that would chemically react with the amorphous semiconductor layer. This can prevent components of the material for the barrier layer from chemically reacting with the semiconductor layer. Consequently, creeping discharge at the outer edge of the common electrode where electric fields concentrate can be prevented.
摘要翻译：本发明的放射线检测器沿着公共电极的外缘在高电阻膜的上表面具有阻挡层，能够防止非晶半导体层与可固化合成树脂之间的化学反应。阻挡层与可固化合成树脂膜粘合，能够防止强度不足，使得温度变化导致阻隔层和可固化合成树脂膜之间的界面分离，从而降低了翘曲和开裂的抑制效果。用于阻挡层的材料是不包括将与非晶半导体层发生化学反应的物质的绝缘材料。这可以防止用于阻挡层的材料的组分与半导体层发生化学反应。因此，可以防止电场集中的公共电极的外缘的沿面放电。

摘要： According to a radiation detector of this invention, a common electrode for bias voltage application and a lead wire for bias voltage supply are connected through a conductive plate as a planarly formed plate interposed therebetween. Since the conductive plate is connected instead of connecting the lead wire directly onto the common electrode, it can prevent damage to a radiation sensitive semiconductor and avoid performance degradation. Since the conductive plate is formed planarly, even if a conductive paste with high resistance is used, connection resistance can be lowered to be comparable to the use of silver paste. That is, the range of selection of the conductive paste is broadened. Also, connection can be made without using an insulating seat and performance degradation can be avoided. As a result, performance degradation can be avoided, without using an insulating seat.

摘要： A radiation detector of this invention has an electrically insulating buffer seat disposed on a front surface of a radiation sensitive semiconductor, in a position outside a radiation detection effective area. A common electrode for bias voltage application is formed to cover the buffer seat. A lead wire for bias voltage supply is connected to a lead wire connection area, located on the buffer seat, of the surface of the common electrode. The buffer seat reduces a shock occurring when the lead wire is connected to the common electrode. As a result, the semiconductor and an intermediate layer are protected from damage which would lead to a lowering of performance. The buffer seat is disposed outside the radiation detection effective area. Thus, the buffer seat is provided without impairing the radiation detecting function.

摘要： It is an object of the invention to improve the quality of images obtained by an X-ray detector. A charge transport layer 13 mainly consisted of diantimony trisulfide, an X-ray detection layer 14 mainly consisted of amorphous selenium and a second electrode film 15 are formed in the same order on the surface of a first electrode film 12 provided on a substrate 11. A voltage whose polarity is positive at the first electrode film 12 and negative at the second electrode film 15 is applied, and the surface of the second electrode film 15 is irradiated with an X-ray. Then, carriers generated in the X-ray detection layer 14 are collected by the first and second electrode films. Since a diode whose anode is an X-ray detection layer 14 side and whose cathode is a charge transport layer 13 side is formed at the interface between the X-ray detection layer 14 and charge transport layer 13 of the X-ray detector 31, no hole is injected from the first electrode film 12 into the X-ray detection layer 14, which prevents any reduction of image quality.

摘要： A two-dimensional array type detecting device of the invention is formed of a detecting side substrate, and a readout side substrate laminated together. In the detecting side substrate, a high resistivity responsive semiconductor film is laminated on a substrate through a common electrode therebetween, and semiconductor films for connection are formed for the respective sections corresponding to a two-dimensional array arrangement. Therefore, leak and expansion of carriers produced in the high resistivity responsive semiconductor are prevented in a direct conversion system, wherein light or radiation enters from a side of the glass substrate, in which the common electrode is not formed. Thus, a detecting sensitivity and space resolution can be improved. Namely, a dynamic range is large, and a crosstalk is small.

摘要： An X-ray image pickup tube converts a transmitted X-ray image into electric signals. The pickup tube includes a target structure having a fluorescent element, and a translucent conductive film for receiving a high voltage, with a photoconductive film laminated thereupon. The fluorescent element receives transmitted X rays in a two-dimensional distribution, and converts them into visible rays in a two-dimensional distribution. The translucnet conductive film is optically coupled to a surface of the fluorescent element opposite from an X-ray incident surface thereof. The photoconductive film includes an amorphors semiconductor layer which converts the visible rays transmitted in a two-dimensional distribution through the translucent conductive film, into electric charges in a two-dimensional distribution, and which multiplies the electric charges in the two-dimensional distribution based on electric fields formed by the high voltage applied to the translucent conductive film. The pickup tube also has a signal reading device in the form of an electron gun or switching elements for scanning a surface of the photoconductive film, as electric signals, a two-dimensional electric potential distribution occurring on the photoconductive film.
