摘要: An isolation trench having localized stressors is provided. In accordance with embodiments of the present invention, a trench is formed in a substrate and partially filled with a dielectric material. In an embodiment, the trench is filled with a dielectric layer and a planarization step is performed to planarize the surface with the surface of the substrate. The dielectric material is then recessed below the surface of the substrate. In the recessed portion of the trench, the dielectric material may remain along the sidewalls or the dielectric material may be removed along the sidewalls. A stress film, either tensile or compressive, may then be formed over the dielectric material within the recessed portion. The stress film may also extend over a transistor or other semiconductor structure.

Partially filling the trench includes forming a liner layer in the trench and forming the first oxide over the liner layer using silane and oxygen precursors at a pressure less than 10 milliTorr (mTorr) and a temperature ranging from about 500° C. to about 1000° C. The method further includes producing a solid reaction product in a top portion of the first oxide. The method further includes sublimating the solid reaction product by heating the substrate in a chamber at a temperature from 100° C. to 200° C. and removing the sublimated solid reaction product by flowing a carrier gas over the substrate. The method further includes filling the trench with a second oxide.
