PURPOSE: A PVA(Polyvinyl Acetate) embossing roller for cleaning a semiconductor and a manufacturing method thereof are provided to prevent fine dust from being reabsorbed on the surface of a PVA roller by eliminating a thin film formed on the surface of a protrusion which is generated in the formation process of the PVA embossing roller. CONSTITUTION: A PVA embossing roller is manufactured. A fixing shaft is inserted into a central part of the PVA embossing roller. The PVA embossing roller is fixed to a rotator of a metal processing shelf. A left and right operation part with a grinding stone moves to the front and back and the left and right. A ground PVA embossing roller is separated.
