Patent ID: 8586399

Claim:
A method of manufacturing a detection device including a plurality of pixels arrayed on a substrate, the pixels each including a switch element disposed on the substrate and a conversion element including an impurity semiconductor layer disposed on an electrode, which is disposed above the switch element and which is isolated per pixel, a protection layer made of an inorganic material, disposed between the substrate and the plurality of electrodes, and covering the plurality of switch elements, and an interlayer insulating layer made of an organic material and disposed over the protection layer, the switch element and the electrode being connected to each other in a contact hole that is formed in the protection layer and the interlayer insulating layer, the method comprising: forming, on the interlayer insulating layer, the electrodes in contact with the interlayer insulating layer and insulating members each made of an inorganic material and disposed to cover the interlayer insulating layer between adjacent two of the electrodes; forming an impurity semiconductor film that covers the insulating members and the electrodes, and that becomes the impurity semiconductor layer; and forming a coating layer such that, when the insulating members are formed, the coating layer covers an area of the protection layer where an orthographically-projected image of a portion of the electrode is positioned, the portion including a level difference located within the contact hole of the interlayer insulating layer.
