Microelectromechanical signal processor fabrication
First Claim
1. A method for fabrication of a microelectromechanical signal processor on a substrate, said method comprising the steps of:
- (a) fabricating a first patterned layer on said substrate;
(b) fabricating a second patterned layer having an opening for anchoring a third patterned layer;
(c) fabricating said third patterned layer;
(d) fabricating a fourth patterned layer having an opening for anchoring a fifth patterned layer;
(e) fabricating said fifth patterned layer; and
(f) etching said fourth layer and said second layer.

Abstract
A micromechanical filter having planar components, and manufacturable using very large scale integrated circuit microfabrication techniques. The input and output transducers are interdigitated comb electrodes. The mechanical coupling between the input and output transducers includes planar flexures, displacement of the electrodes producing bending of the elements of the flexures. By sealing micromechanical filters in a vacuum and providing on-board circuitry, high signal-to-noise ratios and quality factors are achievable. Construction of a real-time spectrum analyzer using many micromechanical resonators, provides a device with high accuracy and a short sample time.
