dc.description.abstract | We investigated the effects of in situ NH3 preannealing immediately before sealing nitride deposition on the wordline sheet resistance (R-s) of a tungsten polymetal gate electrode (W/WNx/poly-Si). While in situ NH3 preannealing is very effective for the suppression of W-O whisker formation, it was found that excessively long-time NH3 preannealing could cause an unexpectedly abnormal increase in the wordline R, of short gate length electrodes, typically < 100 nm. Since X-ray diffraction (XRD) and secondary ion mass spectroscopy (SIMS) analyses reveal that long-time NH3 preannealing results in the nitridation of tungsten sidewall surfaces. the wordline R-s increase in a small-gate-length sample subjected to Iong-time NH3 preannealing is mainly due to tungsten sidewall nitridation, which is localized at the surface region of the tungsten sidewall. In addition, at a Iona-time NH(3-)preannealed gate electrode, an abnormal inflation of the tungsten sidewall occurred due to a slight increment in lattice spacing by tungsten nitridation. | en_US |
