Abstract
Kinetic parameters from studies of deposition on planar deposits are used to predict superconformal filling of fine features during iodine-catalyzed chemical vapordeposition. The mechanism behind the superconformal filling is described and the metrology required to predict it is identified and quantified. The dominant effect is the change of the coverage of adsorbed catalyst with surface area during interface evolution. Experimental filling results are described and shown to be consistent with the predictions. An associated effect on surface roughness of planar deposits is also described.Citation
