Claim 0:
1. A manufacturing method comprising:
providing a structure disposed on a substrate, the structure having first and second layers, wherein the first layer is a sacrificial layer, wherein the second layer is a compressively strained layer disposed on the first layer and the second layer includes a plurality of sublayers arranged as a stack of sublayers of a first type and sublayers of a second type disposed sequentially on top of each other, and wherein the first type of sublayers are germanium sublayers and the second type of sublayers comprise an alloy including germanium and tin, the structure comprising:
first and second members spaced a distance from each other along a direction,
a strip located between the first and second members and extending along an axis intersecting said direction, and
arms connecting the first and second members to a first end of the strip, wherein the first and second members, the strip and the arms comprise respective portions of the first and second layers; and

removing at least a portion of the first layer at the strip and arms such that the strip and arms become suspended and the arms remain anchored to the first layer via the first and second members.
