    Abstract: A semiconductor accelerometer is formed by attaching a semiconductor layer to a handle wafer by a thick oxide layer. Accelerometer geometry is patterned in the semiconductor layer, which is then used as a mask to etch out a cavity in the underlying thick oxide. The mask may include one or more apertures, so that a mass region will have corresponding apertures to the underlying oxide layer. The structure resulting from an oxide etch has the intended accelerometer geometry of a large volume mass region supported in cantilever fashion by a plurality of piezo-resistive arm regions to a surrounding, supporting portion of the semiconductor layer. Directly beneath this accelerometer geometry is a flex-accommodating cavity realized by the removal of the underlying oxide layer. The semiconductor layer remains attached to the handle wafer by means of the thick oxide layer that surrounds the accelerometer geometry, and which was adequately masked by the surrounding portion of the top semiconductor layer during the oxide etch step. In a second embodiment support arm regions are dimensioned separately from the mass region, using a plurality of buried oxide regions as semiconductor etch stops.

    Abstract: A high temperature resist process is combined with microlithographic patterning for the production of materials, such as diamond films, that require a high temperature deposition environment. A conventional polymeric resist process may be used to deposit a pattern of high temperature resist material. With the high temperature resist in place and the polymeric resist removed, a high temperature deposition process may proceed without degradation of the resist pattern. After a desired film of material has been deposited, the high temperature resist is removed to leave the film in the pattern defined by the resist. For diamond films, a high temperature silicon nitride resist can be used for microlithographic patterning of a silicon substrate to provide a uniform distribution of diamond nucleation sites and to improve diamond film adhesion to the substrate. A fine-grained nucleation geometry, established at the nucleation sites, is maintained as the diamond film is deposited over the entire substrate after the silicon nitride resist is removed. The process can be extended to form microstructures of fine-grained polycrystalline diamond, such as rotatable microgears and surface relief patterns, that have the desirable characteristics of hardness, wear resistance, thermal conductivity, chemical inertness, anti-reflectance, and a low coefficient of friction.
