摘要: | In this paper, the effects of dopant distribution in substrate/ back-gate, back bias and metal gate work-function on performance and Vt roll-off of Extremely-Thin Silicon-On-Insulator (ETSOI) MOSFETs with Ultra-Thin Buried OXide (UTBOX) (ES-UB- MOSFETs) were simulated and studied. Lateral Non-uniform Dopant Distribution (LNDD) in substrate was used to enhance scaling capability and improve Vt controllability for ES-UB- MOSFETs. Process and device simulations were conducted to demonstrate the importance of substrate dopant engineering and to search the optimization design conditions for ES-UB-MOSFETs. Fixing long channel Vt at ±0.3V for ES-UB-MOSFETs, LNDD enables gate length to be scaled to 20nm for both n- and p-MOS, which is ~ 10% smaller than that of the ES-UB-MOSFETs with lateral uniform doping in substrate. A novel process flow to form LNDD was proposed and simulated. |
