Abstract: A local area interconnect structure comprising one or more electrically conductive interconnects formed from electrically conductive metal compounds is described and a process for forming same. Electrically conductive metal compounds are selectively deposited in one or more trenches which were previously formed in an insulation layer in a configuration conforming to the desired pattern of the electrically conductive interconnects. A seed layer is first selectively formed on surfaces of the trenches and the electrically conductive metal compound is then selectively deposited over the seed layer in the trench, but not on the exposed surfaces of the insulation layer.

Abstract: Method and apparatus for forming large scale fields suitable for use in the fabrication of integrated circuit structures having submicron dimensions. The method includes subdividing the large scale field into a plurality of subfields along the boundaries of functional components forming a very large scale integrated circuit. Stitching the subfields into the large scale field is then substantially simplified since the number and dimensions of conductive interconnects between the functional components can be more easily accommodated. The large scale field further includes a custom portion and a standard portion of functional components. Reticle formation of the standard portion involves optical correction techniques. Reticle formation of the custom portion may involve standard reticle formation techniques.
