    摘要: Vertical stacks of a metal portion and a semiconductor portion formed on a first substrate are brought into physical contact with vertical stacks of a metal portion and a semiconductor portion formed on a second substrate. Alternately, vertical stacks of a metal portion and a semiconductor portion formed on a first substrate are brought into physical contact with metal portions formed on a second substrate. The assembly of the first and second substrates is subjected to an anneal at a temperature that induces formation of a metal semiconductor alloy derived from the semiconductor portions and the metal portions. The first substrate and the second substrate are bonded through metal semiconductor alloy portions that adhere to the first and second substrates.

    摘要: A dielectric layer is patterned with at least one line trough and/or at least one via cavity. A metallic nitride liner is formed on the surfaces of the patterned dielectric layer. A metal liner is formed on the surface of the metallic nitride liner. A conformal copper nitride layer is formed directly on the metal liner by atomic layer deposition (ALD) or chemical vapor deposition (CVD). A Cu seed layer is formed directly on the conformal copper nitride layer. The at least one line trough and/or the at least one via cavity are filled with an electroplated material. The direct contact between the conformal copper nitride layer and the Cu seed layer provides enhanced adhesion strength. The conformal copper nitride layer may be annealed to covert an exposed outer portion into a contiguous Cu layer, which may be employed to reduce the thickness of the Cu seed layer.

    摘要: A method for fabricating a cell structure includes doping a substrate to form a N-region and a P-region, disposing a first anti-reflective layer on the substrate, disposing a metallic contact paste on the first anti-reflective layer, drying the metallic contact paste to form contacts, disposing a second anti-reflective layer on the first anti-reflective layer and the metallic contacts, and heating the cell structure, wherein heating the cell structure results in metallic contact material penetrating the first anti-reflective layer and contacting the substrate.

    摘要: A semiconductor structure and a method for fabricating the semiconductor structure provide a field effect device, such as a field effect transistor, that includes a spacer shaped metal gate located over a channel within a semiconductor substrate that separates a plurality of source and drain regions within the semiconductor substrate. Within the semiconductor structure, the plurality of source and drain regions is asymmetric with respect to the spacer shaped metal gate. The particular semiconductor structure may be fabricated using a self aligned dummy gate method that uses a portion of a spacer as a self alignment feature when forming the spacer shaped metal gate, which may have a sub-lithographic linewidth.
