  • Abstract
    We report the successful growth of MOS capacitor stacks with low temperature strained epitaxial Ge or Si1-xGex(x=0.9) layer directly on Si substrates, and with HfO2(EOT=9.7 Å) as high-κ dielectrics, both using a novel remote plasma-assisted chemical vapor deposition technique. These novel MOS capacitors, which were fabricated entirely at or below 400°C, exhibit normal capacitance-voltage and current-voltage characteristics.
