    摘要: The invention discloses a process for manufacturing a radiation detector for detecting e.g. 200 eV electrons. This makes the detector suited for e.g. use in an Scanning Electron Microscope.
    The detector is a PIN photodiode with a thin layer of pure boron connected to the p + -diffusion layer. The boron layer is connected to an electrode with an aluminium grid to form a path of low electrical resistance between each given point of the boron layer and the electrode.
    The invention addresses forming the aluminium grid on the boron layer without damaging the boron layer. To that end the grid of aluminium is formed by covering the boron layer completely with a layer of aluminium and then removing part of the layer of aluminium by etching, the etching comprising a first step (304) of dry etching, the step of dry etching defining the grid but leaving a thin layer of aluminium on the part of the boron layer to be exposed, followed by a second step (308) of wet etching, the step of wet etching completely removing the aluminium from the part of the boron layer to be exposed.

    摘要: A light-tight silicon radiation detector. The detector utilizes a silicon substrate (402) having a sensitive volume for the detection of ionizing radiation and a rectifying contact or electrode through which the ionizing radiation may enter. A diffused or boron-implanted p+ layer may act as the rectifying electrode (404) and as an entrance window for the sensitive volume. A first layer of titanium nitride (406) is deposited on the entrance window to prevent light from being admitted to the sensitive volume and to increase the abrasion and corrosion resistance of the detector. Alternatively a titanium nitride layer may be deposited directly on the silicon substrate, said layer acting as a surface barrier or Schottky barrier rectifying contact. A layer of titanium nitride may be deposited on the backside contact wherein this titanium nitride layer serves as an ohmic contact. The second layer may be further utilized as a conductive contact for surface mount connections.

    摘要: The invention relates an x-ray detector module comprising a plurality of silicium-drift detector cells which are arranged next to each other on a sensor chip. Said sensor chip is arranged in a recess of a frame-shaped base support, such that the sensitive chip surface lies in the opening of said frame-shaped base support. The aim of the invention is to improve the signal/base ratio. As a result, a mask (10) is fixed to the side of the base support (2) which is opposite to the recess, said mask covering the outer edge areas of external silicium-drift detector cells of the sensor chip (8) and ridges above the sensor chip (8) protrude into the opening of the base support (2). The ridges are arranged in such a manner that they cover the defining strips which are adjacent to the silicum drift detector cells, in order to protect the external edge areas and the defining strips which are covered by the mask (10) counter to the incident x-ray photons.

    摘要: A device forming a high energy resolution integrated semiconductor DELTA E-E detector telescope is disclosed, in which is formed a very thin DELTA E detector portion (14) primarily fabricated from a first semiconductor wafer which is bonded/silicidized to a second semiconductor wafer forming an E detector portion (18). This DELTA E-E detector provides a well supported very thin DELTA E detector for high resolution. The very thin DELTA E detector portion bonded/silicidized to the E detector portion further provides between each other a buried metallic layer (16) acting as a contact common to the two detectors, which metal layer is thin and presents a low resistivity.

    摘要: A detector (100) for detecting neutrons includes a neutron reactive material (102) adapted to interact with neutrons to be detected and release ionizing radiation reaction products in relation to the interactions with neutrons. The detector also includes a first semiconductor element (101) being coupled with the neutron reactive material (102) and adapted to interact with the ionizing radiation reaction products and provide electrical charges proportional to the energy of the ionizing radiation reaction products. In addition electrodes are arranged in connection with the first semiconductor element (101) for providing charge collecting areas (106) for collecting the electrical charges and to provide electrically readable signal proportional to the collected electrical charges. The thickness of the first semiconductor element (101) is adapted to be electrically and/or physically so thin that it is essentially/practically transparent for incident photons, such as background gamma photons.
