    摘要: Described herein are metal gate electrode stacks including a low resistance metal cap in contact with a metal carbonitride diffusion barrier layer, wherein the metal carbonitride diffusion barrier layer is tuned to a particular work function to also serve as a work function metal for a pMOS transistor. In an embodiment, the work function-tuned metal carbonitride diffusion barrier prohibits a low resistance metal cap layer of the gate electrode stack from migrating into the MOS junction. In a further embodiment of the present invention, the work function of the metal carbonitride barrier film is modulated to be p-type with a pre-selected work function by altering a nitrogen concentration in the film.

    摘要: In one embodiment, a substrate holder comprises a base supporting a substrate that includes a surface having a peripheral region. A cover may be assembled with the base and includes at least one opening exposing only a portion of the surface therethrough. A seal assembly substantially seals a region between the cover and base and further adjacent to the peripheral region of the substrate. An electrode includes at least one contact portion positioned within the region and extending over at least a portion of the peripheral region of the substrate. A compliant member comprises a polymeric material and may be positioned within the region between the at least one contact portion and either the peripheral region of the substrate or the cover. In other embodiments, an electroplating system is disclosed that may employ such a substrate holder.

    摘要: An embodiment mitigates one or more of the limiting factors of fabricating polymer ferroelectric memory devices. For example, an embodiment reduces the degradation of the ferroelectric polymer due to the polymer's reaction with, and migration or diffusion of, adjacent metal electrode material. Further, the ferroelectric polymer is exposed to fewer potentially high temperature or high energy processes that may damage the polymer. An embodiment further incorporates an immobilized catalyst to improve the adhesion between adjacent layers, and particularly between the electrolessly plated electrodes and the ferroelectric polymer.
