An Exact, Algebraic Solution for the Incubation Period of Superfill



Daniel Josell, Thomas P. Moffat, Daniel Wheeler


Recent publications have used the impact of area change coupled with conservation of adsorbed catalyst to quantify the superfill effect of bottom-up feature filling during electrodeposition and chemical vapor deposition. This work describes how that superfilling process can be quantified using fronts that grow from corners where surfaces impinge. The results obtained apply only when catalyst is preadsorbed on the surface, with no subsequent accumulation of consumption. They are therefore of limited use for general process modeling. However, because they are exact solution, they can be used to check the accuracy of models and computer codes concerned with the more general problems of feature filling.
