Summary:A method for fabricating a pad conditioning tool includes the steps: preparing a sapphire substrate with a specific orientation plane, wherein the specific orientation plane is selected from a group consisting of a-plane, c-plane, r-plane, m-plane, n-plane and v-plane; utilizing screen printing technique and a screen plate in order to transfer an image pattern such that upon solidifying one side surface of the sapphire substrate is imprinted with the image pattern; and performing an etching process on the side surface of the sapphire substrate such that the side surface is formed with a plurality of micro particles of specific structures.
