    摘要: A semiconductor device and method to form a semiconductor device is described. The semiconductor includes a gate stack disposed on a substrate. Tip regions are disposed in the substrate on either side of the gate stack. Halo regions are disposed in the substrate adjacent the tip regions. A threshold voltage implant region is disposed in the substrate directly below the gate stack. The concentration of dopant impurity atoms of a particular conductivity type is approximately the same in both the threshold voltage implant region as in the halo regions. The method includes a dopant impurity implant technique having sufficient strength to penetrate a gate stack.

    摘要: A semiconductor device having tipless epitaxial source/drain regions and a method for its formation are described. In an embodiment, the semiconductor device comprises a gate stack on a substrate. The gate stack is comprised of a gate electrode above a gate dielectric layer and is above a channel region in the substrate. The semiconductor device also comprises a pair of source/drain regions in the substrate on either side of the channel region. The pair of source/drain regions is in direct contact with the gate dielectric layer and the lattice constant of the pair of source/drain regions is different than the lattice constant of the channel region. In one embodiment, the semiconductor device is formed by using a dielectric gate stack placeholder.
