A semiconductor device. The device including a substrate having electrical traces, at least one of a MEMS die and a semiconductor chip mounted on the substrate, and a spacer. The spacer has a first end connected to the substrate and includes electrical interconnects coupled to the electrical traces. The at least one MEMS die and a semiconductor chip are contained within the spacer. The spacer and substrate form a cavity which contains the at least one MEMS die and a semiconductor chip. The cavity forms an acoustic volume when the semiconductor device is mounted to a circuit board via a second end of the spacer. |
