Abstract: A method for mass producing silicon type pressure transducers and transducers resultant therefrom are disclosed. In the method, the major components of a plurality of transducers are simultaneously joined together by a field-assisted bonding technique which allows the components to be made of materials having an approximate match in coefficients of thermal expansion and therefore imparts improved performance characteristics to the individual transducers during operation. This method of mass production of transducers reduces the amount of operational steps and significantly reduces the amount of time and labor required for manufacture.
