Patent ID: 7358161

Claim:
A method of forming a transistor device associated with semiconductor-on-insulator construction, comprising: providing a substrate comprising a semiconductor-containing layer over an insulative mass, the insulative mass comprising silicon dioxide; forming a band of material within the insulative mass, the band of the material comprising one or more of nitrogen, argon, fluorine, bromine, chlorine, iodine and germanium; forming a transistor gate proximate the semiconductor-containing layer, the transistor gate defining a channel region within the semiconductor-containing layer, forming a pair of source/drain regions within the semiconductor-containing layer and separated from one another by the channel region, and wherein the pair of source/drain regions are spaced from the insulative mass; wherein the band of the material comprises a lateral width that at least equals a lateral width of the insulative mass; and wherein the band of the material is formed within the insulative mass simultaneously with the semiconductor-containing layer being formed over the insulative mass.
