Abstract:
A method is provided for forming alloy deposits at selected areas on a receiving substrate, including providing a decal alloy carrier, having alloy loadable areas in selected positions thereof, the alloy loadable areas being adapted to being loaded with an alloy mass, mating the decal alloy carrier with the receiving substrate, so that the alloy loadable areas substantially correspond to the selected areas on the receiving substrate, and reflowing the solder alloy masses so as to cause transfer of the alloy from the alloy loadable areas to selected areas on the receiving substrate, such as solder-affine pads, while ensuring that the decal alloy carrier and the receiving substrate are kept in close contact one to another at least during the reflowing. The alloy loadable areas are preferrably recesses in the decal alloy carrier having flat bottoms, which results in relaxed alignment tolerances.
Abstract:
Some embodiments of the present invention provide processes and apparatus for electrochemically fabricating multilayer structures (e.g. mesoscale or microscale structures) with improved endpoint detection and parallelism maintenance for materials (e.g. layers) that are planarized during the electrochemical fabrication process. Some methods involve the use of a fixture during planarization that ensures that planarized planes of material are parallel to other deposited planes within a given tolerance. Some methods involve the use of an endpoint detection fixture that ensures precise heights of deposited materials relative to an initial surface of a substrate, relative to a first deposited layer, or relative to some other layer formed during the fabrication process. In some embodiments planarization may occur via lapping while other embodiments may use a diamond fly cutting machine.
Abstract:
A method of creating a microelectromechanical systems (MEMS) device includes applying a layer of photoresist to a lower layer to create a multilayer MEMS device. The method includes transferring the layer of photoresist to the lower layer. The method can also include spincoating the photoresist onto a release layer, softbaking the spincoated photoresist to at least partially dry it, transferring the photoresist to form a layer of the multilayer MEMS device, and exposing the photoresist to light to crosslink it. The multilayer MEMS device includes a plurality of layers of photoresist.

Abstract:
A semiconductor pressure transducer includes a silicon substrate, a recessed portion in a major surface of the substrate, and a multiple level diaphragm overlying the recessed portion. A selectively etchable spacer material is employed when fabricating the diaphragm by forming successive layers of diaphragm material over the spacer material. Holes through the diaphragm are filled with the selectively etchable material thereby allowing the etching of the spacer material. Support posts can be provided in the recessed portion to help support the diaphragm.
