| 20160056037 | METHOD TO TUNE TIOX STOICHIOMETRY USING ATOMIC LAYER DEPOSITED TI FILM TO MINIMIZE CONTACT RESISTANCE FOR TIOX/TI BASED MIS CONTACT SCHEME FOR CMOS - Methods of depositing and tuning deposition of sub-stoichiometric titanium oxide are provided. Methods involve depositing highly pure and conformal titanium on a substrate in a chamber by (i) exposing the substrate to titanium tetraiodide, (ii) purging the chamber, (iii) exposing the substrate to a plasma, (iv) purging the chamber, (v) repeating (i) through (iv), and treating the deposited titanium on the substrate to form sub-stoichiometric titanium oxide. Titanium oxide may also be deposited prior to depositing titanium on the substrate. Treatments include substrate exposure to an oxygen source and/or annealing the substrate. | 02-25-2016 |
