    摘要： An array of radiation sensing devices, each including a pair of conductor-insulator-semiconductor capacitors, arranged in rows and columns in which the row stripes or lines form row connected capacitors in relation to selected surface regions of a semiconductor substrate and in which the column stripes or lines form column connected capacitors in relation to the selected surface regions. Each of the row stripes overlies first portions of the selected surface regions of a respective row. Each of the column stripes overlies entirely the selected surface regions of a respective column.

    摘要： A low capacitance radiation detector comprises a monocrystalline silicon substrate heavily doped to N type conductivity with a more lightly doped N type conductivity epitaxial layer formed on the substrate. A plurality of heavily doped N type upper surface layer segments are formed in the epitaxial layer. A patterned region of the epitaxial layer, heavily doped to P type conductivity and in the shape of parallel stripes joined at each end by a respective stripe perpendicular to the parallel stripes, is formed in the epitaxial layer and situated between adjacent ones of the upper surface layer segments, with each stripe extending into the epitaxial layer deeper than, and separated from, the upper surface layer segments so as to form a minority charge carrier-collecting PN junction with the epitaxial layer. The parallel stripes are spaced apart from each other by a distance smaller than or comparable to the minority charge carrier recombination diffusion length for the epitaxial layer, and the epitaxial layer thickness is smaller than or comparable to the minority charge carrier recombination diffusion length. In a second embodiment, the epitaxial layer has beveled edges and the heavily doped N type upper surface layer segments formed in the epitaxial layer extend over the beveled edges.

    摘要： In a substrate of semiconductor material of one conductivity type and high resistivity, a thin layer of the same conductivity and low resistivity is provided adjacent a major surface of the substrate. A region of opposite conductivity type is provided in the substrate adjacent the major surface to form a PN junction therewith spaced adjacent to the thin layer. Zero bias is provided on the PN junction. Minority charge carriers generated in the semiconductor substrate underlying the thin layer in response to applied radiation diffuse to the region of opposite conductivity type and are sensed.
