Abstract:
A method of fabricating a crystallographically oriented ferroelectric/pyroelectric film infrared detector using a thin film transfer method, said method of fabricating comprising:(a) depositing a lattice matched reflecting metal layer on a top surface of a circuit, said top surface comprising a plurality of metal structural support members; (b) depositing a rock salt structure material substrate layer on a deposition surface of said metal layer; (c) depositing a lattice matched and crystallographically oriented first electrode layer on a deposition surface of said substrate layer; (d) depositing a lattice matched and crystallographically oriented ferroelectric/pyroelectric film layer on a deposition surface of said first electrode layer; (e) depositing a second electrode layer on a deposition surface of said ferroelectric/pyroelectric film layer; and (f) removing said rock salt structure material substrate.
