Abstract
A microelectromechanical microphone includes: a substrate; a sensor chip, integrating a microelectromechanical electroacoustic transducer; and a control chip operatively coupled to the sensor chip. In one embodiment, the sensor chip and the control chip are bonded to the substrate, and the sensor chip overlies, or at least partially overlies, the control chip. In another embodiment, the sensor is bonded to the substrate and a barrier is located around at least a portion of the sensor chip.
