For instance, for a position at the wafer rim (radial position of 10 cm), a value for r of 0.8 and a growing thickness which is equal to 0.9 times the growing thickness at the center of the wafer are obtained. Therefore, for the example studied here, the profile change is due to the change of the growing thickness rather than due to the change of the conformality (governed by the parameter r in addition to sc which is assumed to be independent of the local fluxes). For other reactor configurations leading to different variations of the fluxes of neutral and ions across the wafer, this behavior can differ
