Method for fabricating semiconductor device

A method for fabricating a semiconductor device includes forming a plurality of plugs over a die region and an edge bead removal (EBR) region of a wafer, forming metal lines coupled to the plugs, removing the metal lines in the EBR region, forming an inter-layer dielectric layer over the wafer, and forming a plurality of contact holes that expose the metal lines by selectively etching the inter-layer dielectric layer through a dry etch process using a plasma etch device.
