In-depth low frequency noise evaluation of substrate rotation and strain engineering in n-type triple gate SOI FinFETs
LFN of conventional, strained, rotated and strained rotated nFinFETs is studied. Strained devices have shown poorer noise and higher Not than conventional ones. Substrate rotation has improved the noise of narrow FinFETs. Maximum Not of conventional devices occurs close to the interface. Maximum Not of strained devices occurs 1.41.5nm away from interface.
