Abstract
A semiconductor radiation detector (1′, 1″, 1′″, 1″″) includes a body of semiconducting material (2) responsive to ionizing radiation for generating electron-hole pairs in the bulk of said body (2). A conductive cathode (4) is disposed on one side of the body (2) and an anode structure (6) is disposed on the other side of the body (2). The anode structure (6) includes a first set of spaced elongated conductive fingers (8) in contact with the body (2) and defining between each pair of fingers thereof an elongated gap (10) and a second set of spaced elongated conductive fingers (12) positioned above the surface of the body (2) that includes spaced elongated conductive fingers (8). Each finger of the second set of spaced elongated conductive fingers (12) overlays, either partially or wholly, the elongated gap between a pair of adjacent fingers of the first set of spaced elongated conductive fingers (8).
