  • Publication number: 20220102521
    Abstract: Low resistance approaches for fabricating contacts, and semiconductor structures having low resistance metal contacts, are described. In an example, an integrated circuit structure includes a semiconductor structure above a substrate. A gate electrode is over the semiconductor structure, the gate electrode defining a channel region in the semiconductor structure. A first semiconductor source or drain structure is at a first end of the channel region at a first side of the gate electrode. A second semiconductor source or drain structure is at a second end of the channel region at a second side of the gate electrode, the second end opposite the first end. A source or drain contact is directly on the first or second semiconductor source or drain structure, the source or drain contact including a barrier layer and an inner conductive structure.

  • Publication number: 20110147831
    Abstract: An exemplary embodiment of a method for forming a gate for a planar-type or a finFET-type transistor comprises forming a gate trench that includes an interior surface. A first work-function metal is formed on the interior surface of the gate trench, and a low-resistivity material is deposited on the first work-function metal using a chemical vapor deposition (CVD) technique, or an atomic layer deposition (ALD) technique, or combinations thereof. Another exemplary embodiment provides that a second work-function metal is formed on the first work-function metal, and then the low-resistivity material is deposited on the first work-function metal using a chemical vapor deposition (CVD) technique, or an atomic layer deposition (ALD) technique, or combinations thereof.
