Abstract :
PMOS transistors with effective channel lengths down to 0.15 mu m have been fabricated on silicon-on-insulator (SOI) films. Gate oxide thicknesses of 5.5 and 10 nm are used. These P/sup +/ gate PMOS devices exhibit excellent short-channel behavior, low-source-drain resistance, and remarkably large current drive and transconductance. for T/sub ox/=5.5 nm, saturation transconductances of 274 mS/mm at 300 K and 352 mS/mm at 80 K are achieved, which are the highest reported values for this oxide thickness. The result is attributed to low series resistance, forward-bias body effect, and the reduction of body charge effect.<>
