Abstract:
Techniques are disclosed for passivation of transistor channel region interfaces. In some cases, the transistor channel region interfaces to be passivated include the interface between the semiconductor channel and the gate dielectric and/or the interface between the sub-channel semiconductor material and isolation material. For example, an aluminum oxide (also referred to as alumina) layer may be used to passivate channel/gate interfaces where the channel material includes silicon germanium, germanium, or a III-V material. The techniques can be used to reduce the interface trap density at the channel/gate interface and the techniques can also be used to passivate the channel/gate interface in both gate first and gate last process flows. The techniques may also include an additional passivation layer at the sub-channel/isolation interface to, for example, avoid incurring additional parasitic capacitance penalty.

Claim (Index 18):
An integrated circuit including at least one transistor, the integrated circuit comprising:\n a substrate including silicon; a body above the substrate and including one or both of germanium or group III-V semiconductor material; a gate electrode at least above the body; a first layer between the gate electrode and the body, the first layer including oxygen and at least one of aluminum and titanium; a second layer between the first layer and the gate electrode, the second layer including one or more high-k dielectric materials; and a first region and a second region, the body between the first and second regions, the first and second regions including semiconductor material.
