Patent ID: 7727794

Claim:
A radiation detector manufacturing method, wherein a photodiode array is manufactured by conducting: a first step of forming, in a semiconductor substrate, formed of a semiconductor of a first conductive type, penetrating wirings that pass through between the respective surfaces of the semiconductor substrate; a second step of adding an impurity to predetermined regions of a surface at one side of the semiconductor substrate to form a plurality of impurity diffusion layers of a second conductive type and forming a plurality of photodiodes arrayed in array form from the respective impurity diffusion layers and the semiconductor substrate; and a third step of providing on the surface at one side of the semiconductor substrate, a resin film that covers at least the regions at which the photodiodes are formed and transmits the light to be detected, such that a surface of the resin film covering at least said regions is flat, the resin film serving as a protective film for the regions at which the photodiodes are formed, the radiation detector manufacturing method comprising: a fourth step of bonding the photodiode array onto a mounting wiring substrate using a flat collet; and a fifth step of mounting a scintillator panel to an incidence surface of the photodiode array.
