  • Patent number: 10468365
    Abstract: In a method for manufacturing a radiation detector, counter pixel electrodes 33 are formed on a counter substrate 2 at positions facing a plurality of pixel electrodes formed on a signal reading substrate, and wall bump electrodes 34 are further formed on the counter pixel electrodes 33. In order to achieve the above, a resist R is applied, and the resist R is exposed to light to form openings O. When Au sputter deposition is performed on the openings O, only some of the Au is deposited on the bottom surface in the openings O as the counter pixel electrodes 33. The rest of the Au is not deposited on the bottom surface in the openings O, and the most of the remaining Au adheres to the inner walls of the openings O to form wall bump electrodes 34. The bump electrodes 34 are cylindrical, making it possible to reduce the pressure acting on the signal reading substrate by an extent corresponding to the decrease in the bonding area in comparison to conventional bump-shaped bump electrodes.

  • Patent number: 10254417
    Abstract: In a radiation detector, a Schottky electrode is formed such that an interdiffusion coefficient between the material of an outermost surface electrode formed on the Schottky electrode and the material of the Schottky electrode is smaller than an interdiffusion coefficient between the material of the outermost surface electrode and Al (aluminum). Consequently, the material of the outermost surface electrode does not diffuse into the Schottky electrode, and Schottky functions can be maintained, and at the same time, the material of the Schottky electrode does not diffuse into the outermost surface electrode, and the outermost surface electrode can be prevented from alloying.

  • Patent number: 9985150
    Abstract: A graphite substrate is processed to have surface unevenness in a range of 1 ?m to 8 ?m. Thereby, a semiconductor film to be laminated on the graphite substrate has a stable film quality, and thus adhesion of the graphite substrate and the semiconductor layer can be enhanced. When an electron blocking layer is interposed between the graphite substrate and the semiconductor layer, the electron blocking layer is thin and thus the surface unevenness of the graphite substrate is transferred onto the electron blocking layer. Consequently, the electron blocking layer also has surface unevenness approximately in such range. Thus, almost the same effect as a configuration in which the semiconductor layer is directly connected to the graphite substrate can be produced.
