Summary:According to an embodiment, a micro-fabricated test structure includes a structure mechanically coupled between two rigid anchors and disposed above a substrate. The structure is released from the substrate and includes a test layer mechanically coupled between the two rigid anchors. The test layer includes a first region having a first cross-sectional area and a constricted region having a second cross-sectional area smaller than the first cross-sectional area. The structure also includes a first tensile stressed layer disposed on a surface of the test layer adjacent the first region.
