Abstract
A method for tuning an electro-mechanical device such as a MEMS device is disclosed. The method comprises operating a MEMS device in a depressurized system and using FIB micromachining to remove a portion of the MEMS device. Additionally, a method for tuning a plurality of MEMS devices by depositing an active layer and then removing a portion of the active layer using FIB micromachining. Also, a method for tuning a MEMS device and vacuum packaging the MEMS device in situ are provided.
