Abstract
A substrate structure includes a substrate, a buffer layer, and a protecting layer. The substrate includes a side surface. The buffer layer is disposed between the side surface of the substrate and the protecting layer, and the hardness of the protecting layer is greater than the hardness of the buffer layer.
Claims9
