Abstract:
A method of fabricating a thin film of layered superlattice material in an integrated circuit comprising the steps of:providing a precursor containing metal moieties in effective amounts for forming a layered superlattice material upon heating said precursor; wherein the layered superlattice material may be represented under the formula: A1w1+a1A2w2+a2. . . Ajwj+ajS1x1+s1S2x2+s2. . . Skxk+skB1y1+b1B2y2+b2. . . Blyl+blQzâˆ’q where A1, A2 . . . Aj represents A-site elements in the perovskite-like structure, S1, S2 . . . Sk represent superlattice generator elements; B1, B2 . . . Bl represent B-site elements in the perovskite-like structure; and Q represents an anion;applying said precursor to a substrate to form a precursor thin film; and exposing said precursor thin film to a substance selected from the group consisting of: (a) a strong oxidizing agent; and (b) oxygen under pressure; to from a metal oxide thin film.
