Abstract
The present application discloses a contact structure, a semiconductor device, and a method for fabricating the semiconductor device. The semiconductor device includes a substrate; an impurity region positioned in the substrate; an intervening conductive layer positioned on the impurity region; a bottom conductive layer positioned on the bottom conductive layer; a conductive capping layer positioned on the bottom conductive layer; a top conductive layer positioned on the conductive capping layer. The intervening conductive layer, the bottom conductive layer, the conductive capping layer, and the top conductive layer configure a contact structure. The bottom conductive layer includes germanium or silicon germanium. The bottom conductive layer includes n-type dopants or p-type dopants.
