    摘要: The present invention provides a digital optical switch apparatus and process for manufacturing the apparatus. The apparatus includes a mirror assembly coupled to a top cap and to a bottom cap. The top and bottom caps each include one or more electrodes that, when energized with electrical energy, move a mirrored surface to one of a plurality of discrete positions. Mirror assemblies can be cascaded to create a packaged assembly having any multiple of discrete positions. The process includes planar micro-machining techniques to create isolated islands for electrical feed through. The process enables mechanical bonding of multiple tiers via a single bond region and through a bond-pad window.

    摘要: An accelerometer (305) for measuring seismic data. The accelerometer (305) includes an integrated vent hole for use during a vacuum sealing process and a balanced metal pattern for reducing cap wafer bowing. The accelerometer (305) also includes a top cap press frame recess (405) and a bottom cap press frame recess (420) for isolating bonding pressures to specified regions of the accelerometer (305). The accelerometer (305) is vacuum-sealed and includes a balanced metal pattern (730) to prevent degradation of the performance of the accelerometer (305). A dicing process is performed on the accelerometer (305) to isolate the electrical leads of the accelerometer (305). The accelerometer (305) further includes overshock protection bumpers (720) and patterned metal electrodes to reduce stiction during the operation of the accelerometer (305).
