摘要:
A method for reducing errors in a tuning fork gyroscope includes determining a first distance, gt, between an upper sense plate and a proof mass and a second distance, gb, between a lower sense plate and the proof mass. The method further includes applying a first voltage, Vt, to the upper sense plate and a second voltage, Vb, to the lower sense plate, wherein the ratio of the first voltage and the second voltage is a function of the first distance and the second distance.
摘要:
A method for producing Microelectromechanical Systems (MEMS) and related devices using Silicon-On-Insulator (SOI) wafer includes providing an SOI wafer, performing a mesa etch to at least partially define the MEMS device, bonding the SOI wafer to an interposer by direct boding, removing the handle layer of the SOI wafer, removing the oxide layer of the SOI wafer, and further etching the device layer of the SOI wafer to define the MEMS device. A structure manufactured according to the above described processes includes an interposer comprising an SOI wafer and a MEMS device mounted on the interposer. The MEMS device comprises posts extending from a silicon plate. The MEMS device is directly mounted to the interposer by bonding the posts of the MEMS device to the device layer of the interposer.
