  1. 1. Investigation of Novel Metal Gate and High-κ Dielectric Materials for CMOS Technologies

    Author : Jörgen Westlinder; Jörgen Olsson; Stefan Bengtsson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; metal gate; high-κ dielectics; titanium nitride; zirconium nitride; MOSFET; thin film; tantalum oxide; aluminum nitride; Elektronik; Electronics; Elektronik;

    Abstract : The demands for faster, smaller, and less expensive electronic equipments are basically the driving forces for improving the speed and increasing the packing density of microelectronic components. Down-scaling of the devices is the principal method to realize these requests. READ MORE

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

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

    Abstract : 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.
