  • Patent number: 10319596
    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.
