A semiconductor device may include, but is not limited to: a semiconductor substrate having an element formation region and a dicing region; an element layer over the element formation region and the dicing region; and a multi-layered wiring structure over the dicing region. The multi-layered wiring structure extends upwardly from the element layer. The multi-layered wiring structure has a groove penetrating the multi-layered wiring structure.
