Abstract

Plasma enhanced chemical vapor deposition (PECVD) can be used to fabricate surfaceswith a wide range of physical and chemical properties and are used in a variety ofapplications. Despite this, the mechanisms by which PECVD films grow are not wellunderstood. Moreover, the species which contribute to film growth can be consideredquite differently depending on the process. Particularly for functionalized plasma polymerfilms, the growth mechanisms are considered with respect to the chemistry of thedepositing species, ignoring the physics of plasmas. Here we analyse the role ions playin the deposition of three common classes of depositing plasmas, and how these closelyrelated fields treat ions very differently.
