Patent ID: 8624194

Claim:
A method of manufacturing a radiation detecting device including a plurality of photodetectors and a scintillator layer provided above the plurality of photodetectors, the method comprising: forming a scintillator layer on a substrate carrying a plurality of photodetectors and a plurality of convex patterns each including a plurality of convexities, the plurality of convex patterns coinciding with the respective photodetectors in a stacking direction, the scintillator layer being formed in such a manner as to extend over the plurality of convex patterns; and forming a crack in a portion of the scintillator layer that coincides, in the stacking direction, with a gap between adjacent ones of the convex patterns by cooling the substrate carrying the scintillator layer, wherein the plurality of convex patterns satisfy the following conditions: 0.6 ≦s/t< 0.9 d<D<4.6h where t denotes a pitch of the convexities in each convex pattern, s denotes a length of an area of each convexity that is in contact with the scintillator layer in each convex pattern, h denotes a height of each convexity in each convex pattern, d denotes a distance between adjacent ones of the convexities in each convex pattern, and D denotes an average distance between adjacent ones of the convex patterns.
