    摘要: Semiconductor devices are formed with a silicide interface between the work function layer and polycrystalline silicon. Embodiments include forming a high-k/metal gate stack by: forming a high-k dielectric layer on a substrate, forming a work function metal layer on the high-k dielectric layer, forming a silicide on the work function metal layer, and forming a poly Si layer on the silicide. Embodiments include forming the silicide by: forming a reactive metal layer in situ on the work function layer, forming an a-Si layer in situ on the entire upper surface of the reactive metal layer, and annealing concurrently with forming the poly Si Layer.

    摘要: Disclosed herein is a method of forming a semiconductor device. In one example, the method includes forming a gate electrode structure above a semiconducting substrate, wherein the gate electrode structure includes a gate insulation layer, a gate electrode, a first sidewall spacer positioned proximate the gate electrode, and a gate cap layer, and forming an etch stop layer above the gate cap layer and above the substrate proximate the gate electrode structure. The method further includes forming a layer of spacer material above the etch stop layer, and performing at least one first planarization process to remove the portion of said layer of spacer material positioned above the gate electrode, the portion of the etch stop layer positioned above the gate electrode and the gate cap layer.
