    摘要: A MOSFET comprising a fully germano-silicided gate electrode having a high work function is disclosed. This gate electrode is formed by a self-aligned reaction process between a silicidation metal and a semiconductor material comprising silicon and germanium. Preferably, the fully germano-silicided gate is formed by a reaction between nickel and SiGe. The work function of the fully germano-silicided gate electrode can be tuned.

    摘要: Under the present invention, a layer of amorphous silicon is formed over a layer of gate dielectric. Over the layer of amorphous silicon, a gate cap dielectric is formed. The layer of amorphous silicon is then confined by at least one spacer, which is deposited under a low temperature process. Once the at least one spacer is in place, the amorphous silicon is exposed to a temperature sufficiently high to convert the amorphous silicon to polysilicon. By waiting until the amorphous silicon is confined within the at least one spacer before converting it to polysilicon, the variation in gate length is reduced.

    摘要: The present disclosure provides a dual workfunction semiconductor device and a method for manufacturing a dual workfunction semiconductor device. The method comprises providing a device on a first region and a device on a second region of a substrate. According to embodiments described herein, the method includes providing a dielectric layer onto the first and second region of the substrate, the dielectric layer on the first region being integrally deposited with the dielectric layer on the second region, and providing a gate electrode on top of the dielectric layer on both the first and second regions, the gate electrode on the first region being integrally deposited with the gate electrode on the second region. The method further includes changing the workfunction of the device on the first region by providing a capping layer onto the first region between the dielectric layer and the gate electrode, and changing the workfunction of the device on the second region by including species at the interface between the dielectric layer and the electrode.
