Gas impingement flux

WebNov 5, 2014 · The result of gas flux distribution is shown in Fig. 4 where each dot represents the impinging gas flux on one measured position; the gas flux impinging on the sample surface is normalized to the highest flux measured by the RGA, which was 3.4 x 10 +9 atoms s −1 µm −2 at the impingement center spot. The image shows a smooth … Webvariation of gas impingement flux versus the considering precursors (P1 to P6) is not very significant. Indeed the precursor size would mainly affect the growth rate via the steric hindrances rather than the impingement flux. We note that the possibility of having SCVD growth can also result in a higher GPC that expected based on ALD data.
