Claim 7:
8. 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, and wherein the second layer is a compressively strained layer disposed on the first layer, the second layer comprising 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,
third and fourth members spaced a distance from each other along said direction, the strip being located between the third and fourth members, and
arms connecting the first and second members to a first end of the strip and additional arms connecting the third and fourth members to a second end of the strip, wherein the first and second members, the strip, the third and fourth members, the arms, and the additional arms comprise respective portions of the first and second layers; and

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