Abstract:
Techniques are disclosed for forming semiconductor integrated circuits including a channel region, a gate dielectric between the gate electrode and the channel region, a first layer between the gate dielectric and the gate electrode, the first layer comprising temperature compensation material. In addition, the integrate circuit includes a source region adjacent to the channel region, a source metal contact on the source region, a drain region adjacent to the channel region, and a drain metal contact on the drain region. The temperature compensation material has a temperature dependent band structure, work-function, or polarization that dynamically adjusts the threshold voltage of the transistor in response to increased operating temperature to maintain the off-state current Ioff stable or otherwise within an acceptable tolerance. The temperature compensation material may be used in conjunction with a work function material to help provide desired performance at lower or non-elevated temperatures.
