    Sammanfattning : This thesis is divided in two parts, one dealing with the depleted Si/Si structure, which is a substrate behaving as a semi-insulating material intended for radio-frequency applications and the other concerning high-k gate dielectrics (dielectrics with high dielectric constant) as the replacement for silicon dioxide as MOS gate dielectric.High frequency applications of CMOS integrated circuits, to lower cost, achieve higher performance and richer functionality, depends partly on the possibility to decrease the substrate coupling between different parts of the circuit.

  4. 3. Vacuum Ultraviolet Scanning Photoelectron Microscopy, Instrumentation & Applications

    Författare :Ulf Johansson; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Photoelectron Microscopy; Spectromicroscopy; Photoemission; Silicon; Oxide desorption; High-Tc superconductor; Physics; Ellipsoidal mirror; Fysik; Chemistry; Kemi; Fysicumarkivet A:1997:Johansson;

    Sammanfattning : This thesis describes the design and characterisation of a vacuum ultraviolet scanning photoelectron microscope as well as results from studies of laterally inhomogeneous surfaces. The instrument utilises synchrotron radiation from an undulator at the 550 MeV storage ring at the MAX-laboratory. LÄS MER
