Abstract
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.
