Abstract: A method and apparatus for packaging a plurality of micro-magnetic switches is described. A bonded substrate structure includes a first substrate, a second substrate, and a magnetic layer. The first substrate has a plurality of cantilevers formed thereon. The second substrate has a first surface that is bonded to the first substrate. Each cantilever of the plurality of cantilevers on the first substrate is housed in a corresponding space formed between the first substrate and the second substrate. The magnetic layer is formed on a second surface of the first and/or second substrate to induce a magnetization in a magnetic material of each housed cantilever. The bonded substrate structure is singulated to form a plurality of separate micro-magnetic switch packages. Each micro-magnetic switch package of the plurality of micro-magnetic switch packages includes at least one housed cantilever.

Abstract: Packages for a micromachined magnetic latching switch, and methods for assembling the packages are described. In one aspect, a substrate is defined by opposing first and second surfaces. A micromagnetic switch integrated circuit (IC) chip is mounted to the first surface. A contact pad on the chip is coupled to a trace on the first surface. A permanent magnet is positioned closely adjacent to the chip. A cap is attached to the first surface. An inner surface of the cap forms an enclosure to enclose the chip on the first surface. The chip can be alternatively mounted to the inner surface of the cap. The chip can be oriented in a standard or flip-chip fashion. In another aspect, a moveable micro-machined cantilever is supported by a surface of a substrate. A cap is attached to the surface. An inner surface of the cap forms an enclosure that encloses the cantilever on the surface of the substrate. A permanent magnet is positioned closely adjacent to the cantilever.
