abstract = {Terbium scandate (TbScO3) and lanthanum scandate (LaScO3)
have been investigated as gate dielectrics for
metal-oxide-semiconductor field-effect transistors on both
silicon-on-insulator (SOI) and strained SOI (sSOI)
substrates. X-ray photoelectron spectroscopy analysis
revealed the presence of a silicate at the interface for
TbScO3 on Si, whereas a silicate/SiO2-like interface was
found for the LaScO3 on Si. A full replacement gate process
was developed to fabricate high-kappa/metal gate fully
depleted transistors on SOI and sSOI. LaScO3 transistors
with a gate length of 2 mu m show excellent characteristics
with steep subthreshold slopes of 72 mV/dec, high Ion/Ioff
ratios, and electron mobility of 180 cm(2)/V . s for SOI and
375 cm(2)/V . s for sSOI at low field, which is superior to
corresponding TbScO3 devices. All sSOI transistors showed 2
times higher electron mobility than SOI reference devices.},
