Abstract

We report here for the first time an evaluation of a polysilicon capped physical vapor deposited (PVD) titanium nitride (TiN) metal gate integration on sub-quarter micron CMOSFETs using bulk Si and FDSOI substrates. In addition to eliminating poly depletion effects and lowering gate line resistance, the use of TiN gate enables lower Vt when used with FDSOI substrates instead of bulk Si. Excellent on-off and short channel characteristics can be obtained with TiN gate. Issues associated with Leff and reliability are also discussed.
