    摘要: One embodiment of the present invention provides a method for fabricating a high-quality metal substrate. During operation, the method involves cleaning a polished single-crystal substrate. A metal structure of a predetermined thickness is then formed on a polished surface of the single-crystal substrate. The method further involves removing the single-crystal substrate from the metal structure without damaging the metal structure to obtain the high-quality metal substrate, wherein one surface of the metal substrate is a high-quality metal surface which preserves the smoothness and flatness of the polished surface of the single-crystal substrate.
