  • Patent number: 11538683
    Abstract: A method deposits an epitaxial layer on a front side of a semiconductor wafer having monocrystalline material. The method includes: providing the semiconductor wafer; arranging the semiconductor wafer on a susceptor; heating the semiconductor wafer to a deposition temperature using thermal radiation directed to the front side and to the rear side of the semiconductor wafer; conducting a deposition gas over the front side of the semiconductor wafer; and selectively reducing an intensity of a portion of the thermal radiation that is directed to the rear side of the semiconductor wafer, as a result of which first partial regions at an edge of the semiconductor wafer, in the first partial regions a growth rate of the epitaxial layer is greater than in adjacent second partial regions given uniform temperature of the semiconductor wafer owing to an orientation of the monocrystalline material, are heated more weakly.

  • Patent number: 11506529
    Abstract: Various embodiments include determining a level of a surface of a fluid and/or for determining a quality of the fluid in a fluid container. An example apparatus comprises a sound transducer module having two sound transducers designed to receive and emit sound signals in such a manner that a superimposition sound signal results when the sound signals are superimposed, and a reference element arranged in the fluid at a predefined distance from the sound transducer module and is designed to reflect the superimposition sound signal. The sound transducer module is designed, by superimposing the at least two sound signals, to emit the superimposition sound signal both in a first direction to the surface of the fluid and in a second direction to the reference element, said second direction running at a predetermined sound signal angle with respect to the first direction.

  • Publication number: 20220063568
    Abstract: Aspects of the disclosure relate to cleaning rotating sensors having a sensor housing with a sensor input surface. For instance, a first signal from a position sensor indicating a current position of the sensor housing may be received. A second signal to activate a liquid nozzle and an air nozzle, the liquid nozzle being configured to provide a spray of liquid and the air nozzle being configured to provide a puff of gas may be received. When to activate the liquid nozzle in order to provide the spray of liquid on the sensor input surface may be determined based on the current position of the sensor housing and the second signal. When to activate the air nozzle in order to provide the puff of gas on the sensor input surface may be determined based on the current position of the sensor housing and the second signal.
