Abstract:
A method for manufacturing a two-dimensional image detector, the two-dimensional image detector including an active matrix substrate and a counter substrate, the active matrix substrate having a pixel-arrayed layer in which pixel electrodes and switching elements are arrayed in a lattice form, the counter substrate having a semiconductor layer with photoconductivity and an electrode section formed so as to face substantially an entirety of a surface of the pixel-arrayed layer, the active matrix substrate being electrically connected to a connection surface of the counter substrate via a conductive material, said method including a step of forming a plurality of protuberance electrodes on the connection surface of the counter substrate, said step of forming the plurality of protuberance electrodes comprising the following substeps:a. forming a mask having openings in a predetermined pattern, on the electrode section; b. processing a mask-covered surface of the electrode section and semiconductor layer by blasting, so that at the openings of the mask the electrode section is removed while grooves are formed on the semiconductor layer; and c. removing the mask.
