摘要:The prent invention provides a method of fabricating a patterned silicon-on-insulator substrate which includes dual depth SOI regions or both SOI and non-SOI
regions within the same substrate. The method of the prent invention includes forming a silicon mask having at least one opening on a surface of Si-containing material, recessing the Si-containing material through the at least one opening using an etching process to provide a structure having at least one recess region and a non-recesd region, and forming a first buried insulating region in the non-recesd region and a cond buried insulating region in the recesd region. In accordance with the prent invention, the first buried insulating region in the non-recesd region is located above the cond buried isolation region in the recesd region. A lift-off step can be employed to remove the first buried insulating region and the material that lies above to provide a substrate containing both SOI and non-SOI regions.skap
