  • Abstract
    High mobility semiconductors such as InGaAs or Ge are needed to continue CMOS scaling. However, the passivation of their surfaces has tended to leave too many interface gap states (Dit) which cause Fermi level pinning, and hinder the operation of the FET. The physical principles of improved passivation are explained, in terms of using gate dielectrics which include a diffusion barrier, and also valence control of the oxide next to the channel.
