Abstract
A light-receiving device array in which a plurality of light-receiving devices are one- or two-dimensionally arranged on a substrate, a scintillator layer is deposited on the light-receiving devices and provided with columnar crystals, and an organic film is formed over the scintillator layer and there outside region of the substrate and it intrudes into gaps among the top part of the columnar crystals to cover the scintillator layer.
Claims33
A radiation detection device comprising:
- a light-receiving device array comprising a plurality of light-receiving devices one- or two-dimensionally arranged on a substrate;
- a scintillator layer having a top surface and side surfaces, deposited on said light-receiving devices and comprising columnar crystals each having at least one side surface facing a side surface of another of the columnar crystals across a gap formed between the side surfaces of the columnar crystals, said scintillator layer being positioned above said substrate with a portion of said substrate surrounding a periphery of said scintillator layer;
- and
- an organic film formed on the top and side surfaces of said scintillator layer and on the portion of said substrate surrounding the periphery of said scintillator layer and extending at least partially into the gaps formed between the side surfaces of the columnar crystals of said scintillator layer.
