Abstract:
A method for adjusting a threshold voltage includes depositing a strained liner on a gate structure to strain a gate dielectric. A threshold voltage of a transistor is adjusted by controlling an amount of strain in the liner to control an amount of work function (WF) modulating species that diffuse into the gate dielectric in a channel region. The liner is removed.

Claim (Index 1):
A method for adjusting threshold voltage, comprising:\n depositing two or more liners on two or more different regions of a device, such that the liners impart two or more different strain levels on respective gate dielectric layers; and introducing work function (WF) modulating species to the gate dielectric layers wherein due to the different strain levels in the gate dielectric layers, different amounts of the WF modulating species diffuse to the gate dielectric layers at a channel region, resulting in different threshold voltage values.
