    摘要: The disclosure relates to a method of forming an n-type doped active area on a semiconductor substrate that presents an improved placement profile. The method comprises the placement of arsenic in the presence of a carbon-containing arsenic diffusion suppressant in order to reduce the diffusion of the arsenic out of the target area during heat-induced annealing. The method may additionally include the placement of an amorphizer, such as germanium, in the target area in order to reduce channeling of the arsenic ions through the crystalline lattice. The method may also include the use of arsenic in addition to another n-type dopant, e.g. phosphorus, in order to offset some of the disadvantages of a pure arsenic dopant. The disclosure also relates to a semiconductor component, e.g. an NMOS transistor, formed in accordance with the described methods.

    摘要: The present invention pertains to formation of a PMOS transistor wherein a layer of silicon or SiGe inhibits p-type dopant from entering into an underlying gate dielectric layer. The p-type dopant can be added to a gate electrode material that overlies the silicon or SiGe layer and can diffuse down toward the silicon or SiGe layer. The layer of silicon or SiGe may be formed to a thickness of about 5 to 120 nanometers and doped with a dopant, such as indium (In), for example, to deter the p-type dopant from passing through the silicon or SiGe layer. The dopant may have a peak concentration within the layer of silicon or SiGe near the interface of the silicon or SiGe layer with the underlying layer of gate dielectric material. Allowing the gate electrode to be doped with the p-type dopant (e.g., boron) facilitates forming the transistor with an associated work function having a desired value (e.g., coincident with a Fermi level of about 4.8 to about 5.6 electron volts).
