Optically-Finished Thin Diamond Substrate or Window of High Aspect Ratio and a Method of Production Thereof

摘要

In a method of forming a diamond film, substrate, or window, a silicon substrate is provided and the diamond film, substrate, or window is CVD grown on a surface of the silicon substrate. The grown diamond film, substrate, or window has an aspect ratio ≧100, wherein the aspect ratio is a ratio of a largest dimension of the diamond film, substrate or window divided by a thickness of the diamond film. The silicon substrate can optionally be removed or separated from the grown diamond film, substrate, or window.
