Abstract:
1. A method of making a MEM switch or tunneling sensor comprising the steps of: (a) defining a cantilevered beam structure and a mating structure on a first substrate or wafer; (b) forming at least one contact structure and a mating structure 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 two mating structures including a protrusion extending from the substrate or wafer from which the at least one protrusion is defined; (c) positioning the mating structure of the first substrate or wafer into a confronting relationship with the mating structure of the second substrate or wafer; (d) bonding a layer associated with said mating structure on the first substrate or wafer with a layer associated with the mating structure on the second substrate or wafer; (e) removing at least a portion of the first substrate or wafer to release the cantilevered beam structure.
