Abstract

A wafer level package for a MEMS device is made by bonding a MEMS wafer and a lid wafer together to form a hermetically sealed cavity. One or more vias filled with conductive or semiconductive material is etched one of the wafers to form one or more rods extending through the wafer. The rods provide electrical connection to components within the hermetically sealed cavity.
