Abstract:
1. A plasma processing reactor, comprising: a substrate holder positioned within a chamber for holding a substrate; a cation species feed to direct a supply of a cation precursor towards the substrate, the cation species feed positioned adjacent to the substrate; an anion species feed to direct a supply of an anion precursor towards a plasma creation region in which a supply of a plasma based anion species can be created as at least part of a plasma; and a hollow cathode positioned between an anode and the cation species feed, the hollow cathode and the anode providing a capacitively coupled configuration, and the plasma creation region is at least partially between the hollow cathode and the anode, wherein, the supply of the cation precursor and the supply of the plasma based anion species to the substrate are intermittently modulated.
