W using SiH 4 0.67 nm/cycle is larger than that using B 2H6 0.31 nm/cycle. Compared to B2H6 precursor, the pre-exposure of SiH 4 precursor on TiN may enhance the nucleation of W during the exposure of wafers to WF6 reduction gas (14). As a result, the growth rate of ALD W using SiH 4 is faster than that using B2H6. Figure 2. Growth rate of ALD W
