Publication number: 20140311243Abstract: An apparatus (36) includes a motion amplification structure (52), an actuator (54), and a sense electrode (50) in proximity to the structure (52). The actuator (54) induces an axial force (88) upon the structure (52), which causes a relatively large amount of in-plane motion (108) in one or more beams (58, 60) of the structure (52). When sidewalls (98) of the beams (58, 60) exhibit a skew angle (28), the in-plane motion (108) of the beams (58, 60) produces out-of-plane motion (110) of a paddle element (62) connected to the end of the beams (58, 60). The skew angle (28), which results from an etch process, defines a degree to which the sidewalls (98) of beams (58, 60) are offset or tilted from their design orientation. The out-of-plane motion (110) of element (62) is sensed at the electrode (50), and is utilized to determine an estimated skew angle (126).Type: ApplicationFiled: April 22, 2013Publication date: October 23, 2014Applicant: FREESCALE SEMICONDUCTOR, INC.Inventors: Aaron A.

The beams (28, 30) are oriented such that lengthwise edges (34, 36) of the beams are beside one another. Isolation segments (38) are interposed between the beams (28, 30) such that a middle portion (40) of each of the beams is laterally anchored to adjacent isolation segments (38). The isolation segments (38) provide electrical isolation between the beams. The beams (28, 30) are anchored to the substrate (22) via compliant structures (61, 65) that isolate the beams from deformations in the underlying substrate. The compliant structures (61, 65) provide electrically conductive paths (96, 98) to the substrate (22) for the beams (28, 30) where the paths are electrically isolated from one another.Type: ApplicationFiled: April 22, 2013Publication date: October 23, 2014Applicant: FREESCALE SEMICONDUCTOR, INC.Inventor: Aaron A.
