Method of manufacturing localized semiconductor-on-insulator (soi) structures in a bulk semiconductor wafer

A method of forming a localized SOI structure in a substrate (10) wherein a trench (18) is formed in the substrate, and a dielectric layer (20) is formed on the base of the trench (18). The trench is filled with semiconductor material (22) by means of epitaxial growth.
