    Abstract: A method for forming a transducer including the step of providing a semiconductor-on-insulator wafer including first and second semiconductor layers separated by an electrically insulating layer. The method further includes depositing or growing a piezoelectric film or piezoresistive film on the wafer, depositing or growing an electrically conductive material on the piezoelectric or piezoresistive film to form at least one electrode, and depositing or growing a bonding layer including an electrical connection portion that is located on or is electrically coupled to the electrode. The method further includes the step of providing a ceramic substrate having a bonding layer located thereon, the bonding layer including an electrical connection portion and being patterned in a manner to generally match the bonding layer of the semiconductor-on-insulator wafer. The method also includes causing the bonding layer of the semiconductor-on-insulator wafer and the bonding layer of the substrate to bond together to thereby mechanically and electrically couple the semiconductor-on-insulator wafer and the substrate to form the transducer, wherein the electrical connection portions of the bonding layers of the semiconductor-on-insulator wafer and the substrate are fluidly isolated from the surrounding environment by the bonding layers.

    Abstract: A harsh environment transducer including a substrate having a first surface and a second surface, wherein the second surface is in communication with the environment. The transducer includes a device layer sensor means located on the substrate for measuring a parameter associated with the environment. The sensor means including a single crystal semiconductor material having a thickness of less than about 0.5 microns. The transducer further includes an output contact located on the substrate and in electrical communication with the sensor means. The transducer includes a package having an internal package space and a port for communication with the environment. The package receives the substrate in the internal package space such that the first surface of the substrate is substantially isolated from the environment and the second surface of the substrate is substantially exposed to the environment through the port. The transducer further includes a connecting component coupled to the package and a wire electrically connecting the connecting component and the output contact such that an output of the sensor means can be communicated. An external surface of the wire is substantially platinum, and an external surface of at least one of the output contact and the connecting component is substantially platinum.
