发明名称 Structure and manufacturing method of inversed microphone module and microphone chip component
摘要 An inversed microphone module is provided. The module includes a substrate, a microphone chip, a back acoustic cavity cover, and a sealing material. The substrate has a plurality of connection pads and an acoustic hole. The microphone chip has a first surface and an opposite second surface. A plurality of electrically bonding portions and an acoustic sensing are disposed on the first surface. The microphone chip is electrically coupled to the connection pads of the substrate through the electrically bonding portions, and the acoustic hole corresponds to the acoustic sensing portion. The back acoustic cavity cover is fixed to the second surface and defines a back acoustic cavity with the acoustic sensing portion and the microphone chip. The sealing material encapsulates the microphone chip and covers the substrate, so that the sealing material, the substrate, the acoustic sensing portion, and the first surface define a front acoustic cavity.
