    • An x-ray examination apparatus includes an imaging arrangement, devised for performing fluoroscopy. Which has image sensors that are efficiently optically coupled with an x-ray sensitive radiation conversion screen. Consequently, the image sensors produce an electrical signal having a high signal-to-noise ration when low doses of x-radiation are administered. An x-ray conversion screen is provided with a tapetum filter so as to concentrate light in the forward direction. Furthermore, the x-ray conversion screen is preferably fitted with a light reflecting layer for reflecting light that has been reflected by the tapetum filter, said light reflecting layer being transparent for x-radiation. Further concentration of light in the forward direction is achieved by placing a light-transparent material having a suitable refractive index between the radiation conversion screen and lenses that concentrate the light onto the image sensors. Semiconductor image sensors in the form of charge-coupled devices are provided for converting a visible image into an electronic video signal. In order to improve the effectiveness of the CCDs, weak avalanching is applied so as to increase both sensitivity and signal-to-noise ratio of the sensors.

    • A semiconductor device, for example a diode (200), having a pn junction (101) has an insulating material field shaping region (201) adjacent, and possibly bridging, the pn junction. The field shaping region (201) preferably has a high dielectric constant and is coupled via capacitive voltage coupling regions (204,205) to substantially the same voltages as are applied to the pn junction. When a reverse voltage is applied across the pn junction (101) and the device is non-conducting, a capacitive electric field, is present in a part of the field shaping region which extends beyond a limit of the pn junction depletion region which would exist in the absence of the field shaping region (201), the electric field in the field shaping region inducing a stretched electric field limited to a correspondingly stretched pn junction depletion region (208,209) and an increased reverse breakdown voltage of the device.

    • A semiconductor device includes a programmable element having a doped semiconductor region (4) and a conductor region (6) which are separated from one another by at least a portion of an insulating layer (5). The conductor region (6) is of a material suitable for forming a rectifying junction (8) with the material of the semiconductor region (4). To achieve a comparatively high conductivity connection to the semiconductor region (4), the element is further provided with a contact region (3) which has a comparatively low electrical resistance compared with the semiconductor region (4). The contact region (3) is provided at a side of the semiconductor region (4) remote from the insulating layer (5) and is separated from the insulating layer (5) by the semiconductor region (4). Both the semiconductor region (4) and the contact region (5) are laterally bounded by an isolating region (7) at opposing sides. The invention thus offers a device provided with a programmable element of a substantially more compact structure than a comparable conventional programmable element.
