    摘要: In a replacement gate approach in sophisticated semiconductor devices, the place-holder material of gate electrode structures of different type are separately removed. Furthermore, electrode metal may be selectively formed in the resulting gate opening, thereby providing superior process conditions in adjusting a respective work function of gate electrode structures of different type. In one illustrative embodiment, the separate forming of gate openings in gate electrode structures of different type may be based on a mask material that is provided in a gate layer stack.

    摘要: Methods are provided for fabricating integrated circuits having controlled threshold voltages. In accordance with one embodiment a method includes forming a gate dielectric overlying an N-doped silicon substrate and depositing a layer of titanium nitride and a layer of tantalum nitride overlying the gate dielectric. A sub-monolayer of tantalum oxide is deposited overlying the layer of tantalum nitride by a process of atomic layer deposition, and oxygen is diffused from the tantalum oxide through the tantalum nitride and titanium nitride.

    摘要: When forming sophisticated high-k metal gate electrode structures on the basis of a replacement gate approach, the fill conditions upon filling in the highly conductive electrode metal, such as aluminum, may be enhanced by removing an upper portion of the final work function metal, for instance a titanium nitride material in P-channel transistors. In some illustrative embodiments, the selective removal of the metal-containing electrode material in an upper portion of the gate opening may be accomplished without unduly increasing overall process complexity.

    摘要: By locally heating isolation trenches with different annealing conditions, a different magnitude of intrinsic stress may be obtained in different isolation trenches. In some illustrative embodiments, the different anneal temperature may be achieved on the basis of an appropriate mask layer, which may provide a patterned optical response for a lamp-based or laser-based anneal process. Consequently, the intrinsic stress of isolation trenches may be specifically adapted to the requirements of circuit elements, such as N-channel transistors and P-channel transistors.
