    Abstract: A through substrate via is formed by disposing a quantity of solder material at the top of a through hole formed in a substrate, coating the hole with a wetting layer, and melting the solder material such that it flows into the hole. The solder material may alloy with the wetting layer, freezing upon formation of the alloy. Subsequent processing steps may be performed at temperatures higher than the melting point of the solder material.

    Abstract: A MEMS-based system and a method are described for separating a target particle from the remainder of a fluid stream. The system makes use of a unique, microfabricated movable structure formed on a substrate, which moves in a rotary fashion about one or more fixed points, which are all located on one side of the axis of motion. The movable structure is actuated by a separate force-generating apparatus, which is entirely separate from the movable structure formed on its substrate. This allows the movable structure to be entirely submerged in the sample fluid.

    Abstract: A method for forming a cavity in a microfabricated structure, includes the sealing of that cavity with a low temperature solder. The method may include forming a sacrificial layer over a substrate, forming a flexible membrane over the sacrificial layer, forming a release hole through a flexible membrane to the sacrificial layer, introducing an etchant through the release hole to remove the sacrificial layer, and then sealing that release hole with a low temperature solder.

    Abstract: A method for forming a feature in a device layer, including forming a first layer of a liftoff material and a second layer of photoresist over the liftoff material, exposing the photoresist and developing the photoresist and the liftoff layer. The photoresist develops at a slower rate than the liftoff layer. The development results in a first opening in the lift off layer and a second opening in the photoresist layer wherein the first opening is smaller than the second opening because of the different developing rates. The device layer is then dry etched or ion milled through the opening. Subsequent removal of the first layer and second layer leaves a clean surface of the patterned device layer, without the fences that can be formed using other methods.

    Abstract: A method for forming through silicon vias (TSVs) in a silicon substrate is disclosed. The method involves forming a silicon post as an substantially continuous annulus in a first side of a silicon substrate, removing material from an opposite side to the level of the substantially continuous annulus, removing the silicon post and replacing it with a metal material to form a metal via extending through the thickness of the substrate. The substantially continuous annulus may be interrupted by at least one tether which connects the silicon post to the silicon substrate. The tether may be formed of a thing isthmus of silicon, or some suitable insulating material.

    Abstract: Systems and methods for forming an encapsulated device include a substantially hermetic seal which seals a device in an environment between two substrates. The substantially hermetic seal is formed by an alloy of two metal layers, one having a lower melting temperature than the other. The metal layers may be deposited two substrates, along with a raised feature formed under at least one of the metal layers. The two metals may form an alloy of a predefined stoichiometry in at least two locations on either side of the midpoint of the raised feature. The formation of the alloy may be improved by the use of an organic wetting layer adjacent to the lower melting temperature metal. Design guidelines are set forth for reducing or eliminating the leakage of molten metal into the areas adjacent to the bondlines.

    Abstract: Systems and methods for forming a magnetostatic MEMS switch include forming a movable beam on a first substrate, forming the electrical contacts on a second substrate, and coupling the two substrates using a hermetic seal. A shunt bar on the movable plate may close the switch when lowered onto the contacts. The switch may generally be closed, with the shunt bar resting on the contacts. However, a magnetically permeable material may also be inlaid into the movable plate. The switch may then be opened by placing either a permanent magnet or an electromagnet in proximity to the switch.
