Abstract
A method to deposit a layer of harder thin film substrate onto a softer substrate. In particular, the present invention provides a method to deposit a layer of sapphire thin film on to a softer substrate e.g. quartz, fused silica, silicon and (toughen) glass. This combination is better than pure sapphire substrate.
