Strained gate-all-around semiconductor devices formed on globally or locally isolated substrates are described. In one embodiment, the polymer contains a hydroxyalkyl acrylate ester which is crosslinked with a titanium-containing chelated metal alkoxide. A magnification varying action of a zooming lens is controlled by a lens microcomputer according to the rotation of the zoom ring detected by a rotation detecting circuit. The cut-outs may be partially or fully filled with a a paramagnetic or diamagnetic filler material. Then, the content responder generates a second content based on the second request.
