Abstract:
1. A method for forming a coating over a surface, comprising: using a source of precursor material; transporting the precursor material to a reaction location adjacent a surface to be coated; and depositing a hybrid layer over the surface by chemical vapor deposition using the source of precursor material, wherein the hybrid layer consists essentially of a mixture of polymeric silicon and inorganic silicon, wherein the weight ratio of polymeric silicon to inorganic silicon is in the range of 95:5 to 5:95, and wherein the polymeric silicon and the inorganic silicon are created from the same source of precursor material; wherein at least an 0.1 μm thickness of the hybrid layer is deposited under the same reaction conditions for all the reaction conditions in the deposition process; wherein the water vapor transmission rate is less than 10
