  • Patent number: 10199317
    Abstract: An electronic package includes a circuit structure having a first metal layer, a packaging layer formed on the circuit structure, and a second metal layer formed on the packaging layer and separated from the first metal layer at a distance. The first metal layer and the second metal layer constitute an antenna structure. Since the second metal layer is formed on a portion of a surface of the packaging layer, a propagating wave emitted by the first metal layer cannot pass through the second metal layer, but a surface of the packaging layer not covered by the second metal layer. Therefore, the propagating wave can be transmitted to a predetermined target, and the electronic package performs the function of an antenna.

  • Patent number: 8946838
    Abstract: A radiation converter includes a directly converting semiconductor layer having grains whose interfaces predominantly run parallel to a drift direction—constrained by an electric field—of electrons liberated in the semiconductor layer. Charge carriers liberated by incident radiation quanta are accelerated in the electric field in the direction of the radiation incidence direction and on account of the columnar or pillar-like texture of the semiconductor layer, in comparison with the known radiation detectors, cross significantly fewer interfaces of the grains that are occupied by defect sites. This increases the charge carrier lifetime/mobility product in the direction of charge carrier transport. Consequently, it is possible to realize significantly thicker semiconductor layers for the counting and/or energy-selective detection of radiation quanta. This increases the absorptivity of the radiation converter which in turn makes it possible to reduce a radiation dose applied to the patient.

  • Patent number: 8937360
    Abstract: In one preferred embodiment, a semiconductor diode includes a first layer formed with a p-type semiconductor, a second layer formed with an n-type semiconductor, and a third active depletion layer contained between the first and second layers. The third layer is formed with a radioisotope of the p-type and n-type semiconductors (preferably Si 32) such that initial emission of beta particles begins in the active depletion region and substantially all of the emitted beta particles are contained within the first, second and third layers during operation. The p-type and n-type layers each have sufficient depth to contain substantially all of beta particles emitted from the depletion layer. The depth of each of the p-type and n-type layers is substantially equal to or greater than the maximum beta emission depth of the radioisotope.
