  • Patent number: 7915592
    Abstract: The invention relates to a detector for determining the position and/or energy of photons and/or charged particles. Said detector comprises a plurality of diodes made of a semi-conductor material, n-contacts (1) and p-contacts (4), the n-contacts being provided by dividing an n-layer into individual segments. Said segments of the n-layer are 20-500 ?m wide. Said detectors are produced by diffusing ions on the side of the semi-conductor material in order to produce an n-contact. A metallic layer is metallized thereon. Trenches are etched between the segments by means of lithography for the segmentation thereof. The inventive detector is high-powered and inter alia enables a high local resolution and high counting rates.

  • Patent number: 7338829
    Abstract: The invention relates to a method for producing a detector for determining the energy of photons and charged particles; to be precise, a so-called ?E detector or transmission detector. The invention also relates to a detector that can be produced by using said method. The aim of the invention is to provide a method for producing a detector of the aforementioned type that is stable over a long period of time and in which dead zones are distinctly minimized. The invention also aims to provide a detector of this type. To these ends, the inventive method is used to produce a Si(Li) substrate having a p+ layer and an n layer. These can be layers produced according to the prior art. According to the inventive method, the n layer is partially removed, for example, by chemical etching, honing or by lapping. Lapping, in particular, has proven to be effective. This reduces the zone that is ineffective in a detector of the aforementioned type. The detector is produced from the substrate treated in this manner.

Said detector comprises a plurality of diodes made of a semi-conductor material, n-contacts (1) and p-contacts (4), the n-contacts being provided by dividing an n-layer into individual segments. Said segments of the n-layer are 20-500 &mgr;m wide. Said detectors are produced by diffusing ions on one side of the semi-conductor material in order to produce an n-contact. A metallic layer is metallised thereon. Trenches are etched between the segments by means of lithography for the segmentation thereof. The inventive detector is high-powered and inter alia enables a high local resolution and high counting rates.

  • Patent number: 4415916
    Abstract: Germanium detectors usable for charged particle spectroscopy and capable of enduring overvoltage without impairment are produced by first implanting phosphorus ions of high energy in a small dose and then implanting more phosphorus ions of lower energy in a large dose. The low energy ions reduce surface resistance without impairing the improved properties of withstanding overvoltage that are provided by the high energy implantation. The p.sup.+ contact is provided by boron ion implantation in a conventional manner. "Dead zones" on both sides have been found to have a very small thickness of 0.3 .mu.m.

  • Patent number: 4166218
    Abstract: The distortion of the electric field in a p-i-n diode detector produced by lectrically active layer build-up on the exposed surface of the i zone is removed by irradiating the exposed i zone surface with a light source having the intensity of a few milliwatts.
