  • Patent number: 6803612
    Abstract: On a substrate, first and second electrical connecting elements of an integrated circuit are disposed next to one another along a first direction. The first electrical connecting element is at a first distance from the second electrical connecting element. First and interconnects are disposed on the substrate, the first interconnect being connected to the first electrical connecting element and the second interconnect being connected to the second electrical connecting element. Third and fourth electrical connecting elements are disposed on the substrate and the first and second interconnects are disposed between the third and fourth electrical connecting elements and therebetween are at a second distance from one another, the second distance being smaller than the first distance.

  • Patent number: 6737748
    Abstract: In the fabrication of stacked vias, metal islands referred to as landing pads are introduced for the purpose of contact-connection between the vias that are arranged one above the other. The metal islands project laterally beyond the vias to a significant extent on account of the line shortening effect. The vias arranged in layers lying one above the other are laterally offset with respect to one another. The landing pad of the invention is configured as an interconnect running between the vias. On account of the line shortening effect, which is less critical for longer tracks, contact areas provided at the ends of the interconnect do not have to be chosen to be as large as the square contact areas of conventional metal islands and can therefore be accommodated to save more space on a circuit layout to be miniaturized. The shrink factor of such a semiconductor structure is increased.

  • Patent number: 6559547
    Abstract: The semiconductor structure has a layer structure formed from a metalization layer and a dielectric layer. The metalization layer is patterned and has contact areas. The dielectric layer is composed of a depositable material and covers the metalization layer. The contact areas are formed from many contiguous individual structures, which are so narrow that the depositable material does not form, over the individual structures, any areas which run parallel to the metalization layer. The grid of contiguous individual structures forms a contact area which causes dielectric layer elevations which are particularly low and therefore easy to planarize.

  • Patent number: 6429503
    Abstract: A connection element in an integrated circuit having a layer structure disposed between two conductive structures. The layer structure is formed by an insulating layer, which can be destroyed by application of a predetermined voltage, and a silicon layer. The insulating layer adjoins a first conductive structure made of tungsten.
