Abstract:
Semiconductor contact architectures are provided, wherein contact metal extends into the semiconductor layer to which contact is being made, thereby increasing contact area. An offset spacer allows a relatively deep etch into the semiconductor material to be achieved. Thus, rather than just a flat horizontal surface of the semiconductor being exposed for contact area, relatively long vertical trench sidewalls and a bottom wall are exposed and available for contact area. The trench can then be filled with the desired contact metal. Doping of the semiconductor layer into which the contact is being formed can be carried out in a manner that facilitates an efficient contact trench etch process, such as by, for example, utilization of post trench etch doping or a semiconductor layer having an upper undoped region through which the contact trench etch passes and a lower doped S/D region. The offset spacer may be removed from final structure.

Claim (Index 26):
An integrated circuit including at least one transistor, the integrated circuit comprising:\n a body including semiconductor material; a gate structure at least over the body, the gate structure including a gate electrode and a gate dielectric, wherein the gate dielectric is between the gate electrode and the body; a source region and a drain region, the body between the source and drain regions, wherein the source and drain regions include semiconductor material; a first trench in the source region and a second trench in the drain region, wherein the first trench extends down at least 20 nanometers (nm) from a top surface of the source region, and the second trench extends down at least 20 nm from a top surface of the drain region; and a first contact structure in the first trench and a second contact structure in the second trench, the first and second contact structures including metal.
