Abstract:
An electrical device including a first semiconductor device having a silicon and germanium containing source and drain region, and a second semiconductor device having a silicon containing source and drain region. A first device contact to at least one of said silicon and germanium containing source and drain region of the first semiconductor device including a metal liner of an aluminum titanium and silicon alloy and a first tungsten fill. A second device contact is in contact with at least one of the silicon containing source and drain region of the second semiconductor device including a material stack of a titanium oxide layer and a titanium layer. The second device contact may further include a second tungsten fill.

Claim (Index 8):
An electrical device comprising:\n a p-type semiconductor device present in a first region of a substrate, the p-type semiconductor device including at least one of a silicon and germanium containing source and drain region; an n-type semiconductor device in a second region of the substrate; a dielectric layer formed over the source and drain region; a first device contact formed through the dielectric layer to at least one of said silicon and germanium containing source and drain region of the p-type semiconductor device, the first device contact including a metal liner of an aluminum, titanium and silicon alloy at a base of the first device contact and a first tungsten fill; and a second device contact to a source and drain region of the n-type semiconductor device, the second device contact including a titanium oxide liner in contact with the source and drain of the n-type semiconductor device, a titanium metal line on the titanium oxide liner, and a second tungsten fill on the titanium metal liner.
