High-performance undoped-body 8-nm-thin SOI field-effect transistors
Abstract
We have fabricated undoped-body short-channel extremely thin silicon-on-insulator (ETSOI) field-effect transistors (FETs) with 8-nm SOI thickness that exhibit the expected short-channel benefit compared with doped partially depleted SOI (PDSOI) FETs. Using a source/drain extension (SDE) last process with the SDE implants activated with diffusionless laser anneal, we demonstrate that the series resistance penalty can be minimized, which leads to ETSOI FET drive currents that are comparable to those of conventional thick-body PDSOI FETs. © 2008 IEEE.
