Abstract:
1. A method of forming a semiconductor structure, said method comprising: forming a dielectric template layer on a substrate; patterning said dielectric template layer to form at least one trench therein, wherein a top surface of said substrate is physically exposed within each of said at least one trench; forming a rare-earth oxide fin portion at a lower portion of each of said at least one trench by depositing a rare-earth oxide material; forming a semiconductor fin portion at an upper portion of each of said at least one trench by depositing a semiconductor material; and recessing said dielectric template layer selective to said semiconductor fin portion and said rare-earth oxide fin portion, wherein a remaining portion of said dielectric template layer constitutes a dielectric material layer having a top surface that is recessed relative to a top surface of said semiconductor fin portion.
