Abstract
A method for fabricating a semiconductor device is provided. A first active region and a second active region are defined in a substrate. An electrode covering the first active region and the second active region is formed on the substrate. A first sacrificial layer is formed on the second active layer. A first work function electrode is formed on the first active layer by performing a first doping process to a portion of the electrode. The first sacrificial layer is removed. A second sacrificial layer is formed on the first active layer.
