LAMINATED SEMICONDUCTOR SENSOR WITH VIBRATING ELEMENT AND ASSOCIATED METHOD AND PRODUCT

摘要

LAMINATED SEMICONDUCTOR SENSOR WITH VIBRATING ELEMENT AND ASSOCIATED METHOD AND PRODUCT An electromechanical sensor is provided which comprises: a first silicon wafer which defines a resonant element; wherein the resonant element is doped with approximately the same impurity concentration as a background dopant concentration of the first wafer; and a second single crystal wafer which defines a device for coupling mechanical stress from the second wafer to the resonant element; wherein the first and second wafers are fusion bonded together.
