Abstract:
1. An MEMS microphone component, comprising an MEMS chip having an electrical contact, an ASIC chip having an electrical contact, an internal interconnection of MEMS chip and ASIC chip, and a plated-through hole through the MEMS chip or through the ASIC chip, wherein the MEMS chip and the ASIC chip are arranged one above another, the internal interconnection comprises a direct interconnection of the electrical contact of the MEMS chip with the electrical contact of the ASIC chip, the internal interconnection or at least one of the electrical contacts of the chips is interconnected via the plated-through hole with an external electrical terminal of the component which is arranged on that side of the ASIC chip which faces away from the MEMS chip or on that side of the MEMS chip which faces away from the ASIC chip, a gap is arranged between the MEMS chip and the ASIC chip, a frame arranged in the gap and partially enclosing a space between the MEMS chip and the ASIC chip, the MEMS chip comprises a sensor electrode, and the frame is not completely closed and a sound entry opening is formed at a position where a section of the frame is absent.
