Abstract
A substrate coating and a method of forming the same are provided. The substrate coating includes a first layer formed on a substrate, in which the composition of the first layer includes at least silicon-rich-carbon, and the amount of silicon is about equal to or greater than the amount of carbon; and a second layer formed on the first layer, in which the composition of the second layer includes at least fluorine doped diamond-like-carbon. The substrate coating not only is easy to clean, has good wearing performance, and provides a smooth surface, but also has better adhesion to prevent peeling off.
