Abstract:
An electrical contact structure (an MIS contact) includes one or more conductors (M-Layer), a semiconductor (S-Layer), and an interfacial dielectric layer (I-Layer) of less than 4 nm thickness disposed between and in contact with both the M-Layer and the S-Layer. The I-Layer is an oxide of a metal or a semiconductor. The conductor of the M-Layer that is adjacent to and in direct contact with the I-Layer is a metal oxide that is electrically conductive, chemically stable and unreactive at its interface with the I-Layer at temperatures up to 450° C. The electrical contact structure has a specific contact resistivity of less than or equal to approximately 10 −5 -10 −7  Ω-cm 2  when the doping in the semiconductor adjacent the MIS contact is greater than approximately 2×10 19  cm −3  and less than approximately 10 −8  Ω-cm 2  when the doping in the semiconductor adjacent the MIS contact is greater than approximately 10 20  cm −3 .

Claim (Index 1):
An electrical contact structure including a conductor; a semiconductor and an interfacial dielectric layer disposed between and in contact with both the conductor and the semiconductor, wherein the conductor is a conductive metal oxide, and the interfacial dielectric layer has a thickness in the range 0.2 nm to 4 nm and comprises one of: WO3, TiO2, MgO, Al2O3, HfO2, ZrO2, Ta2O5, V2O5, BaZrO3, La2O3, Y2O3, HfSiO4, ZrSiO4, CoO, NiO, GaO, SrTiO3, or (Ba,Sr)TiO3.
