  • Method for producing a self-aligning masking layer
    Patent number: 10468248
    Abstract: In various embodiments, a method is provided. The method may include forming a buried electrically charged region at a predefined position in a first layer in such a way that the buried electrically charged region generates an electric field having a lateral inhomogeneous field distribution above the first layer, and forming a second layer above the first layer using the field distribution in such a way that a structure of the second layer correlates with the position of the buried electrically charged region.
    Type: Grant

  • Test apparatus and test method
    Patent number: 9699753
    Abstract: A test apparatus for testing a base station of a wireless communication system, comprises a downlink port, which receives a downlink signal from the base station, an uplink port, which emits an uplink signal to the base station, a signal processing unit, which is coupled to the downlink port and analyzes the downlink signal for timing information and generates a timing synchronization signal based on the downlink signal, and a signal generator, which is coupled to the signal processing unit and the uplink port and generates a predetermined signal frame and emits the generated predetermined signal frame based on the synchronization signal via the uplink port to the base station.
