Hydrophilic coatings, methods for depositing hydrophilic coatings, and improved deposition technology for thin films

Abstract From the Canadian patent

The invention provides certain embodiments that involve sputtering techniques for , applying a mixed oxide film comprising silica and titania. In these embodiments, the , techniques involve sputtering at least two targets in a common chamber (e.g. in a shared gaseous atmosphere). A first of these targets includes silicon while a second , of the targets , includes titanium. Further the invention provides embodiments involving a substrate bearing , a hydrophilic coating which can be deposited by sputtering or any other suitable thin film , deposition technique. The invention also provides techniques and apparatuses useful for , depositing a wide variety of coating types. For example the …
