In this paper, strain effects on silicon n-channel gate-all-around (GAA) jucntionless field effect transistor (JLFET) are studied. By using tensile strain SiN layer, drive currents of the JLFETs show enhancement of up to 42%. The high performance strained JLFETs exhibit superior gate control (Ion/Ioff >109) and ideal S.S. (65 mV/dec.) as a channel width scales down to 20 nm. Drive currents and...
In0.53Ga0.47As channel MOSFETs were fabricated on 300 mm Si substrate. The epitaxial In0.53Ga0.47As channel layer exhibits high Hall electron mobility comparable to those grown on lattice matched InP substrates. Excellent device characteristics (SS∼95 mV/dec., Ion/Ioff ∼105, DIBL ∼51 mV/V at Vds = 0.5V for Lg=150 nm device) with good uniformity across the wafer were demonstrated. The extracted high...
Continuously down-scaling EOT and improving mobility are required for CMOS device. Small 0.6~1 nm EOT and low Vt of ~0.15 V are achieved in CMOS by using higher κ gate dielectric and novel process. The ultimate EOT scaling is limited by the inserted ultra-thin SiON interfacial layer in high-κ/Si to reduce the mobility degradation. Further mobility improvement is obtained by using Ge channel MOSFET...
