Abstract

We demonstrate that a single monolayer of alkyl-trichlorosilane Molecules, covalently grafted to the native oxide of a silicon substrate, allows to fabricate silicon based MIS (Metal-Insulator-Semiconductor) devices with excellent electrical properties. The thickness of the organic monolayer is in the range 1.5–2.8 nm, corresponding to long alkyl chains with 8 to 18 carbon atoms. We have fabricated MIS capacitors with a leakage current density as low as 10-8 A/cm2 at 6 MV/cm, high dielectric breakdown field (12 MV/cm), electrically active defect density lower than 1011 cm-2, and low field dc conductivity as low as 10-16–10-15 Scm-1. Thermal stability has been demonstrated up to 450 °C.
