Glancing angle deposition (GLAD) on a smooth substrate has certain limitations, which may be overcome if nanoparticles are deposited first. This study compares the growth of silver columns on a smooth substrate and over pre‐deposited small copper (Ø16 nm) and big C:H plasma polymer nanoparticles (Ø110 nm). Cu nanoparticles help to the growth of the columns but their surface density does not play a major role. C:H nanoparticles ensure the growth of the column from each particle and therefore increased surface density of C:H nanoparticles results in an increased number of columns. In addition, the columns grow even at very small angles of incidence (40°). At high angles of incidence secondary columns start to grow on primary columns and also on the smooth substrate surface in between them.
