Summary: | A manufacturing method of polishing pad dresser of sapphire disc comprises the following steps: providing a sapphire wafer having a specific axis direction; the specific axis direction being one of a axis direction, c axis, r axis, m axis, n axis and v axis; using a screen plate to transfer a transfer pattern to at least one surface of the sapphire wafer by way of screen printing, and solidifying the transfer pattern through a solidification means; and performing an etching process to form a plurality of microstructures having a specific shape on the surface of the sapphire wafer. The microstructure is dressing grains of the polishing pad dresser. |
