WebFeb 15, 2011 · The nucleation and growth characteristics of CVD-W on Ti/TiN barrier layers with SiH 4 and H 2 reduction chemistries are presented. In particular, the reaction between WF 6 (precursor used for depositing W) and the underlying Ti of the barrier stack was studied to better understand the chemistry of ‘volcano’ formation - a phenomena that … WebJun 2, 2015 · This paper reports on the chemical vapor-deposition of tungsten (CVD W) by the reduction of WF 6 using Si, silane (SiH 4) polysiiane (Si 2 H 6 and Si 3 H 8: Si n H 2n+2), diborane (B 2 H 6), phosphine (PH 3), and H 2.These depositions can be changed from selective to blanket configuration by increasing the deposition temperature.
