Abstract

This invention relates to a method of forming a precursor for chemical vapour deposition including the steps of: (a) forming metal ions at a source, (b) introducing the ions into a reaction chamber; and (c) exposing the ions to a gas or gasses within the chamber to react with the ions to form the precursor.
