    Abstract: Embodiments include methods of forming an nFET-tuned gate dielectric and a pFET-tuned gate dielectric. Methods may include forming a high-k layer above a substrate having a pFET region and an nFET region, forming a first sacrificial layer, a pFET work-function metal layer, and a second sacrificial layer above the first high-k layer in the pFET region, and an nFET work-function metal layer above the first high-k layer in the nFET region and above the second sacrificial layer in the pFET region. The first high-k layer then may be annealed to form an nFET gate dielectric layer in the nFET region and a pFET gate dielectric layer in the pFET region. The first high-k layer may be annealed in the presence of a nitrogen source to cause atoms from the nitrogen source to diffuse into the first high-k layer in the nFET region.

    Abstract: Methods of self-aligned multiple patterning and structures formed by self-aligned multiple patterning. A mandrel line is patterned from a first mandrel layer disposed on a hardmask and a second mandrel layer disposed over the first mandrel layer. A first section of the second mandrel layer of the mandrel line is removed to expose a first section of the first mandrel layer. The first section of the first mandrel layer is masked, and the second sections of the second mandrel layer and the underlying second portions of the first mandrel layer are removed to expose first portions of the hardmask. The first portions of the hardmask are then removed with an etching process to form a trench in the hardmask. A second portion of the hardmask is masked by the first portion of the first mandrel layer during the etching process to form a cut in the trench.
