Abstract:
1. A method of forming a radio frequency (“RF”) device including at least one MEMS device comprising the steps of: fabricating a first module from a first plurality of low-temperature co-fired ceramic (“LTCC”) layers, the first plurality of layers forming at least a first circuit used in the operation of the MEMS device; fabricating a second module from a second plurality of low-temperature co-fired ceramic (“LTCC”) layers, the second plurality of layers forming at least a second circuit used in the operation of the MEMS device; polishing a surface of a front layer of the first module to be used as a substrate after fabrication of the first module is completed; fabricating on the front layer the at least one MEMS device using MEMS processing; and bonding the first and second modules together to thereby form a cavity containing the at least one MEMS device.
