  • Patent number: 8110495
    Abstract: A multilayer wiring structure of a semiconductor device having a stacked structure is arranged to restrain reliability degradation due to stress applied to the region of wiring between opposite upper and lower plugs. The rate of overlap of contact surface between upper plug and wiring on contact surface between lower plug and wiring, is small to the extent that no void is generated. The multilayer wiring structure is produced such that no grain boundary is contained in the region of wiring between upper and lower plugs. The difference in thermal expansion coefficient between the material of wiring and the material of upper and lower plugs, is small to the extent that no void is generated.

  • Patent number: 6022804
    Abstract: An integrated circuit having a multi-layered metal wiring structure with interlayer insulating films therebetween. A small cutout is made in a metal wiring when it is desirous to have the metal wiring touch a contact formed in a through hole passing through said cutout. A larger cutout is made in a metal wiring when it is desirous to have the metal wiring remain spaced from a contact formed in a through hole passing through said cutout.

  • Patent number: 5986313
    Abstract: There is formed an isolation which surrounds an active region of a semiconductor substrate. Formed over the active region and on the isolation, respectively, are a gate electrode and two gate interconnections on both sides thereof. Between the gate electrode and the gate interconnections are located two first interspaces each of which is smaller in width than a specified value and a second interspace which is larger in width than the specified value and interposed between the two first interspaces. In forming side walls on both side faces of the gate electrode and gate interconnections by depositing an insulating film on the substrate, the first interspaces are buried with the insulating film. Thereafter, a metal film is deposited on the substrate, followed by chemical mechanical polishing till the gate electrode, gate interconnections, and side walls become exposed.

  • Patent number: 5834369
    Abstract: There are provided the steps of: forming a connection hole in an interlayer insulating film overlying a lower metal interconnection; forming a W plug in the connection hole; forming a first metal film and a second metal film over the interlayer insulating film and the W plug; forming an interconnection underlying film by using a photoresist mask with no alignment margin; and forming a diffusion preventing film made of a titanium fluoride or the like over the W plug, while etching away the exposed part of the first metal film. Reciprocal diffusion of tungsten and aluminum is prevented by the titanium fluoride or the like, thereby preventing the formation of an alloy having high electric resistivity.
