Abstract:
1. A MEMS-microphone comprising a MEMS-transducer having a signal output, an IC-chip having a signal input, a substrate, a signal line, a conducting structure, and a bump connection between the substrate and the MEMS-transducer or between the substrate and the IC-chip forming a part of the signal line; where the MEMS-transducer and the IC-chip are arranged on the substrate, the signal line electrically connects the signal output of the MEMS-transducer with the signal input of the IC-chip, a DC bias voltage is provided by the IC-chip to the MEMS-transducer via the signal line, the conducting structure is electrically connected to a DC potential different from the DC bias voltage, and a minimum lateral distance between the signal line and the conducting structure is kept of at least 200 μm.
