Abstract:
Some embodiments of the present invention provide processes and apparatus for electrochemically fabricating multilayer structures (98) (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 (292, 294, 296, 298) that ensures precise heights of deposited materials relative to an initial surface of a substrate (82), 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 (408).
Abstract:
The present invention relates to a process for forming microstructures on a substrate. A plating surface is applied to a substrate. A first layer of photoresist is applied on top of the plating base. The first layer of photoresist is exposed to radiation in a pattern to render the first layer of photoresist dissolvable in a first pattern. The dissolvable photoresist is removed and a first layer of primary metal is electroplated in the area where the first layer of photoresist was removed. The remainder of the photoresist is then removed and a second layer of photoresist is then applied over the plating base and first layer of primary metal. The second layer of photoresist is then exposed to a second pattern of radiation to render the photoresist dissolvable and the dissolvable photoresist is removed. The second pattern is an area that surrounds the primary structure, but it does not entail the entire substrate. Rather it is an island surrounding the primary metal. The exposed surface of the secondary metal is then machined down to a desired height of the primary metal. The secondary metal is then etched away.
Abstract:
The invention concerns various embodiments directed to various microdevices, including sensors, actuators, valves, scanning mirrors, accelerometers, switches, and the like. In some embodiments the devices are formed via electrochemical fabrication (EFAB tm ). In particular, the invention concerns a microdevice comprising an electrostatically actuated micro-mirror scanning system comprising contoured electrodes that allow a reduced drive voltage without hindering mirror movement.
