  • Miniature microphone assembly with hydrophobic surface coating
    Patent number: 8542850
    Abstract: A miniature microphone assembly comprises a capacitive-microphone transducer, a microphone carrier, and an integrated circuit die. The capacitive-microphone transducer includes a microphone-electrical contact or terminal. The microphone carrier comprises a carrier electrical contact or terminal formed on a first surface of the microphone carrier. An integrated circuit die includes a die electrical terminal operatively coupled to signal amplification or signal conditioning circuitry of the integrated circuit die. The first surface of the microphone carrier comprises a hydrophobic layer or coating. The side surfaces of the integrated circuit die and/or the capacitive-microphone transducer may also include the hydrophobic layer or coating.
