Abstract:
A strip detector to detect ionizing particles and/or radiation, comprising a silicon substrate having a first surface, a plurality of n-doped regions spaced from each other as strips and voltage supply regions on said first surface, a plurality of p-doped regions on said first surface and alternating between said n-doped regions, a first insulating layer on said plurality of n-doped regions and said p-doped regions, and metal strips disposed on said first insulating layer to be above said n-doped regions and insulated by said first insulating layer from said n-doped regions,wherein at least one further insulating layer is provided directly on said first insulating layer, and at least one of said further insulating layers is a discontinuous insulating layer having a discontinuity at a position located above an intermediate zone of one of said p-doped region between two of said n-doped regions, such that said discontinuous insulating layer covers lateral areas of said intermediate zone, andsaid p-doped regions, having been formed by a homogeneous large-area implantation following a deposition of said further insulating layer, has a distribution of a concentration of a p-type doping material along a lateral direction of said strip detector such that the concentration of said doping material in said intermediate zone below the discontinuity of the discontinuous insulating layer is higher than in the zones of said p-doped region directly bordering on said n-doped regions.
