    Abstract: 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).

    Abstract: An accelerometer (305) which comprises a measurement mass assembly having top capacitor electrode (705), with one or more re-entrant openings or grooves (1405), a bottom capacitor electrode (805), with one or more re-entrant openings (1410), and/or a mass electrode pattern (910, 915), which also includes one or more re-entrant openings or grooves (1415, 1420). A re-entrant opening or groove is an opening or groove formed in an element whereby the opening or groove is larger toward the center of the element than at the surface of the element. Re-entrant openings or grooves (1405, 1410, 1415, 1420) reduce fluid damping thereby reducing the amount of thermo-mechanical noise and permit increased sealing pressure of the accelerometer (305) thereby lowering manufacturing costs and increasing production yields.

    Abstract translation: 包括具有顶部电容器电极（705），一个或多个凹入开口或凹槽（1405），底部电容器电极（805）的测量质量组件的加速度计（305），具有一个或多个凹入开口 和/或质量电极图案（910,915），其还包括一个或多个凹入开口或凹槽（1415,1420）。 凹入开口或凹槽是在元件中形成的开口或凹槽，由此开口或凹槽朝向元件的中心比在元件的表面处更大。 凹入开口或凹槽（1405,1410,1415,1420）减少流体阻尼，从而减少热机械噪声的量并允许加速度计（305）的增加的密封压力，从而降低制造成本并提高产量。
