摘要:A micro-electro-mechanical microphone comprising: a substrate (2); a sensorchip (5), which is coupled to the substrate (2) and integrates a micro-electro-mechanicalelectro-acoustic transducer (35); a control chip (6), which is joined to the substrate (2) andis operatively coupled to the sensor chip (5); a bonding ring (16), which surrounds thesensor chip (5) and the control chip (6); a cap (3), which is coupled to the substrate (2) viathe bonding ring (16) and forms an acoustic chamber (4) that houses the control chip (6)and the sensor chip (5); a barrier (18), which extends between the bonding ring (16) andthe sensor chip (5) at a first distance and a second distance, respectively, therefrom, fordefining a first trench (19) between the bonding ring (16) and the barrier (18) and asecond trench (25) between the barrier (18) and the sensor chip (5).
