Zusammenfassung:A lithographic method and a device manufactured thereby are provided to reduce processing steps and costs and to increase a throughput by performing a simultaneous edge bead removal process to remove both edge beads of a top-coating layer and a resist layer. A part of an anti-reflective coating adjacent to a peripheral part of a substrate is removed from the substrate provided with the anti-reflective coating to be extended to or beyond a peripheral edge of the substrate by using a back-side removal process. A layer of radiation sensitive material is deposited on the anti-reflective coating. A top-coating layer is deposited on the layer of radiation sensitive material. A part of the layer of radiation sensitive material and a part of the top-coating layer are simultaneously removed from a periphery of an area adjacent to the peripheral part of the substrate by using a top-side removal process. A process for removing a part of the anti-reflective coating includes a process for removing an edge bead of the anti-reflective coating.
