Summary:Thin-body transistors with silicide source/drains were fabricated
with gate-lengths down to 15 nm. Complementary low-barrier silicides
were used to reduce contact and series resistance. Minimum gate-length
transistors with Tox=40 Å show PMOS
|Idsat|=270 μA/μm and NMOS |Idsat|=190
μA/μm with Vds=1.5 V, |Vg-Vt|=1.2
V and, Ion/Ioff>104. A simple
transmission model, fitted to experimental data, is used to investigate
effects of oxide scaling and extension doping
