Single precursor species continuummodel of FEBID
The single precursor species continuummodel of FEBID assumes a weak precursor–substrate interaction of the van der Waals type and relies on a Langmuir adsorption description neglecting possible interactions between the adsorbed precursor molecules. The
composition by variation of the dwell time can be devised. In the next subsection the continuummodel will therefore be extended to a multicomponent variant.
Multicomponent extension of the continuummodel
The extension of the model described above to the multicomponent case was first introduced by Lobo and

modeling of tip–surface interactions for the case of a corrugated surface. We discuss the issues that arise when the surface is corrugated on relatively small length scales (our best measurements on SiO2 yield a correlation length of 8–10 nm). We develop a continuummodel that explicitly accounts for a
0.26 nm to the surface). The limits on wa–s carry over directly into limits on Wt–s, as we only integrate the tip potential where the integrand is defined. Thus within our continuummodel with a perfectly rigid tip and substrate, we cannot generally take the tip into the regime in which the overall
