  1. 11. Novel concepts for advanced CMOS : Materials, process and device architecture

    Författare :Dongping Wu; KTH; []
    Nyckelord :CMOS technology; MOSFET; high-k; gate dielectric; ALD; surface pre-treatment; metal gate; poly-SiGe; strained SiGe; surface-channel; buried-channel; notched gate;

    Sammanfattning : The continuous and aggressive dimensional miniaturization ofthe conventional complementary-metal-oxide semiconductor (CMOS)architecture has been the main impetus for the vast growth ofIC industry over the past decades. As the CMOS downscalingapproaches the fundamental limits, unconventional materials andnovel device architectures are required in order to guaranteethe ultimate scaling in device dimensions and maintain theperformance gain expected from the scaling.
