Abstract
NH3 plasma grown ultrathin (<75 angstroms) nitride films on strained Si have been oxidized using O2- and N2O-plasma. It is observed that the electrical properties and reliability of metal insulator semiconductor capacitors with N2O-plasma treated nitride films are better than those using O2-plasma treated films. N2O-plasma treatment of nitride films has resulted in a low level of insulator charge density (Qf/q, 1.6×1011 cm-2), a high breakdown voltage (approximately 10-11 MV cm), a high charge-to-breakdown value (QBD, 11.7 C cm-2) and low leakage current.
