Abstract

Gate stacks containing rare earth oxides of Gd₂O₃ and Y₂O₃ as alternative high permittivity gate dielectrics for Si was investigated. The growth and interfaces of thin dielectric films on semiconductors was controlled using ultrahigh vacuum deposition. The interfaces achieved in the gate stacks enabled the electrical, chemical, and structural studies to elucidate the critical materials integration issues for CMOS scaling. The requirements included morphology dependence, interfacial structure and reaction, thermal stability and gate electrode compatibility.
