W volcano is one of the defects in semiconductor devices. The presence of defects causes metal line bridges and thus device malfunction. The decomposition of SiH_4 gas into Si atoms as nucleation sites is crucial for W film deposition. Here, we investigate the phenomenon in which the flowing time of SiH_4 gas appears to dominate both W volcano formation and the degree of W film filling in a hole; the density of W volcanoes is increased with an increase of SiH_4 flowing time. The volcanofree process and step-coverage of a W plug with various SiH_4 flowing times are evaluated, and a formation mechanism is also proposed.
