1. A Micro-Electro-Mechanical Systems (MEMS) device anchor system, comprising:
- a trace anchor bonded to a substrate;
a device anchor bonded to the substrate;
an anchor flexure configured to flexibly couple the trace anchor and the device anchor to substantially prevent transmission of a stress induced in the trace anchor from being transmitted to the device anchor; and
a flexure coupled between the device anchor and a MEMS mechanism, wherein movement of the MEMS mechanism generates forces that are transmitted to the device anchor via the flexure, and wherein the forces are not substantially transmitted to the trace anchor via the anchor flexure.

Abstract
Anchor systems and methods anchor components of a Micro-Electro-Mechanical Systems (MEMS) device to a substrate. An exemplary embodiment has a trace anchor bonded to a substrate, a device anchor bonded to the substrate, and an anchor flexure configured flexibly couple the trace anchor and the device anchor to substantially prevent transmission of a stress induced in the trace anchor from being transmitted to the device anchor.

8. An anchor system anchoring a Micro-Electro-Mechanical Systems (MEMS) mechanism to a substrate, comprising:
-
a trace anchor mesa on a substrate; a trace anchor bonded to the trace anchor mesa on the substrate, wherein the trace anchor is electrically coupled to the trace, and wherein the trace induces stress into the trace anchor in response to the bonding of the trace anchor to the trace anchor mesa on the substrate; a device anchor bonded to the substrate; a means for flexibly coupling and electrically coupling the trace anchor and the device anchor to substantially prevent transmission of the stress induced in the trace anchor from being transmitted to the device anchor. - View Dependent Claims (9)
