Abstract
A microelectromechanical systems (MEMS) component 20 includes a portion 32 of a MEMS structure 30 formed on a semiconductor substrate 34 and a portion 36 of the structure 30 formed in a non-semiconductor substrate 22. The non-semiconductor substrate 22 is in fixed communication with the semiconductor substrate 34 with the portion 32 of the MEMS structure 30 being interposed between the substrates 34 and 22. A fabrication method 96 entails utilizing semiconductor thin-film processing techniques to form the portion 32 on the semiconductor substrate 34, and utilizing a lower cost processing technique to fabricate the portion 36 in the non-semiconductor substrate 22. The portions 32 and 36 are coupled to yield the MEMS structure 30, and the MEMS structure 30 can be attached to another substrate as needed for additional functionality.
