Abstract
A microelectromechanical systems (MEMS) pressure sensor device () includes a substrate structure () having a cavity () formed therein and a substrate structure () having a reference element () formed therein. A sense element () is interposed between the substrate structures () and is spaced apart from the reference element (). The sense element () is exposed to an external environment () via one of the cavity () and a plurality of openings () formed in the reference element (). The sense element () is movable relative to the reference element () in response to a pressure stimulus () from the environment (). Fabrication methodology () entails forming () the substrate structure () having the cavity (), fabricating () the substrate structure () including the sense element (), coupling () the substrate structures, and subsequently forming () the reference element () in the substrate structure ().
