Paper Title:
Electrical Properties of High-K LaLuO3 Gate Oxide for SOI MOSFETs
  Abstract

The paper presents the results of electrical characterization of MOS capacitors and SOI MOSFETs with novel high-κ LaLuO3 dielectric as a gate oxide. The energy distribution of interface state density at LaLuO3/Si interface is presented and typical maxima of 1.2×1011 eV–1cm–2 was found at about 0.25 eV from the silicon valence band. The output and transfer characteristics of the n- and p-MOSFET (channel length and width were 1 µm and 50 µm, respectively) are presented. The front channel mobility appeared to be 126 cm2V–1s–1 and 70 cm2V–1s–1 for n- and p-MOSFET, respectively. The front channel threshold voltages as well as the density of states at the back interface are presented.
