    Abstract: A method of making a micro electro-mechanical switch or tunneling sensor. A cantilevered beam structure and a mating structure are defined on an etch stop layer on a first substrate or wafer; and at least one contact structure and a mating structure are defined on a second substrate or wafer, the mating structure on the second substrate or wafer being of a complementary shape to the mating structure on the first substrate or wafer. A bonding layer, preferably a eutectic bonding layer, is provided on at least one of the mating structures. The mating structure of the first substrate is moved into a confronting relationship with the mating structure of the second substrate or wafer. Pressure is applied between the two substrates so as to cause a bond to occur between the two mating structures at the bonding or eutectic layer. Then the first substrate or wafer and the etch stop layer are removed to free the cantilevered beam structure for movement relative to the second substrate or wafer.

    Abstract: A three axis MEM tunneling/capacitive sensor and method of making same. Cantilevered beam structures for at least two orthogonally arranged sensors and associated mating structures are defined on a first substrate or wafer, the at least two orthogonally arranged sensors having orthogonal directions of sensor sensitivity. A resonator structure of at least a third sensor is also defined, the third sensor being sensitive in a third direction orthogonal to the orthogonal directions of sensor sensitivity of the two orthogonally arranged sensors and the resonator structure having a mating structure thereon. Contact structures for at least two orthogonally arranged sensors are formed together with mating structures on a second substrate or wafer, the mating structures on the second substrate or wafer being of a complementary shape to the mating structures on the first substrate or wafer. The mating structures of the first substrate are disposed in a confronting relationship with the mating structures of the second substrate or wafer. A eutectic bonding layer associated with one of the mating structures facilitates bonding between the respective mating structures. At least a portion of the first substrate or wafer is removed to release the cantilevered beam structures and the resonator structure.

    Abstract: A method of making a micro electromechanical switch or tunneling sensor. A cantilevered beam structure and a mating structure are defined on a first substrate or wafer; and at least one contact structure and a mating structure are defined on a second substrate or wafer, the mating structure on the second substrate or wafer being of a complementary shape to the mating structure on the first substrate or wafer. At least one of the mating structures includes a protrusion extending from a major surface of at least one of said substrates. A bonding layer, preferably a eutectic bonding layer, is provided on at least one of the mating structures. The mating structure of the first substrate is moved into a confronting relationship with the mating structure of the second substrate or wafer. Pressure is applied between the two substrates so as to cause a bond to occur between the two mating structures at the bonding or eutectic layer. Then the first substrate or wafer is removed to free the cantilevered beam structure for movement relative to the second substrate or wafer.

    Abstract: A method of making a micro electromechanical gyroscope. A cantilevered beam structure, first portions of side drive electrodes and a mating structure are defined on a first substrate or wafer; and at least one contact structure, second portions of the side drive electrodes and a mating structure are defined on a second substrate or wafer, the mating structure on the second substrate or wafer being of a complementary shape to the mating structure on the first substrate or wafer and the first and second portions of the side drive electrodes being of a complementary shape to each other. A bonding layer, preferably a eutectic bonding layer, is provided on at least one of the mating structures and one or the first and second portions of the side drive electrodes. The mating structure of the first substrate is moved into a confronting relationship with the mating structure of the second substrate or wafer. Pressure is applied between the two substrates so as to cause a bond to occur between the two mating structures at the bonding or eutectic layer and also between the first and second portions of the side drive electrodes to cause a bond to occur therebetween. Then the first substrate or wafer is removed to free the cantilevered beam structure for movement relative to the second substrate or wafer. The bonds are preferably eutectic bonds.
