  • Abstract
    Higher-κ dielectric LaLuO3, deposited by MBD, with TiN as gate stack was integrated into SiGe p-MOSFETs. The transistors showed good characteristics. An interfacial layer between LaLuO3 and TiN was found, resulting in a smaller-than-normal CET. MBD deposition leads to unconformity on sidewall of the transistor, inducing a gate leakage path.
