    摘要: The work function of a high-k gate electrode structure may be adjusted in a late manufacturing stage on the basis of a lanthanum species in an N-channel transistor, thereby obtaining the desired high work function in combination with a typical conductive barrier material, such as titanium nitride. For this purpose, in some illustrative embodiments, the lanthanum species may be formed directly on the previously provided metal-containing electrode material, while an efficient barrier material may be provided in the P-channel transistor, thereby avoiding undue interaction of the lanthanum species in the P-channel transistor.

    摘要: A method for formally verifying the equivalence of an architecture description with an implementation description. The method comprises the steps of reading an implementation description, reading an architecture description, demonstrating that during execution of a same program with same initial values an architecture sequence of data transfers described by the architecture description is mappable to an implementation sequence of data transfers implemented by the implementation description, such that the mapping is bijective and ensures that the temporal order of the architecture sequence of data transfers corresponds to the temporal order of the implementation sequence of data transfers, and outputting a result of the verification of the equivalence of the architecture description with the implementation description.

    摘要: In a replacement gate approach in sophisticated semiconductor devices, the placeholder 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: In sophisticated semiconductor devices, the threshold voltage adjustment of high-k metal gate electrode structures may be accomplished by a work function metal species provided in an early manufacturing stage. For this purpose, a protective sidewall spacer structure is provided, which is, in combination with a dielectric cap material, also used as an efficient implantation mask during the implantation of extension and halo regions, thereby increasing the ion blocking capability of the complex gate electrode structure substantially without affecting the sensitive gate materials.
