Claim Text:
1. A semiconductor-on-insulator (SOI) structure comprising: a patterned layer formed in an insulating material of the SOI structure, the patterned layer consisting of an excavated region and a pattern region; a strain layer located beneath the patterned layer and in the excavated region and on the pattern region; an active layer located above the strain layer and the patterned layer; a field effect transistor formed in the active layer, wherein the field effect transistor comprises a source, a drain, and a channel; and a handle layer located above the active layer; wherein the channel lies completely within a lateral extent of the pattern region; wherein the source and the drain each lie only partially within the lateral extent of the pattern region; and wherein the strain layer alters a carrier mobility of the channel.
