Claim Text:
1. A method, comprising: forming a trench in a layer of insulating material that is positioned above a substrate comprised of a first semiconductor material, said trench exposing a surface of said substrate, said trench having a width at a bottom of said trench that is less than or equal to 20 nm and a depth that is 60 nm or less; and performing an epitaxial deposition process to form a stable replacement fin material above said exposed surface of said substrate, wherein said replacement fin has a height that is 60 nm or less and it is fully strained in a direction that corresponds to an axial length direction of said replacement fin, wherein said replacement fin is comprised of a second semiconductor material that is different than said first semiconductor material and wherein said replacement fin material has a defect density of 10
