    Abstract: An interconnect structure is provided that includes at least one patterned and cured photo-patternable low k material located on a surface of a patterned and cured oxygen-doped SiC antireflective coating (ARC). A conductively filled region is located within the at least one patterned and cured photo-patternable low k material and the patterned and cured oxygen-doped SiC ARC. The oxygen-doped SiC ARC, which is a thin layer (i.e., less than 400 angstroms), does not produce standing waves that may degrade the diffusion barrier and the electrically conductive feature that are embedded within the patterned and cured photo-patternable low k dielectric material and, as such, structural integrity is maintained. Furthermore, since a thin oxygen-doped SiC ARC is employed, the plasma etch process time used to open the material stack of the ARC/dielectric cap can be reduced, thus reducing potential plasma damage to the patterned and cured photo-patternable low k material.

  • Patent number: 8013364
    Abstract: A structure having air gaps between interconnects is disclosed. A first insulating material is deposited over a workpiece, and a second insulating material having a sacrificial portion is deposited over the first insulating material. Conductive lines are formed in the first and second insulating layers. The second insulating material is treated to remove the sacrificial portion, and at least a portion of the first insulating material is removed, forming air gaps between the conductive lines. The second insulating material is impermeable as deposited and permeable after treating it to remove the sacrificial portion. A first region of the workpiece may be masked during the treatment, so that the second insulating material becomes permeable in a second region of the workpiece yet remains impermeable in the first region, thus allowing the formation of the air gaps in the second region, but not the first region.

  • Patent number: 7986040
    Abstract: During the patterning of via openings in sophisticated metallization systems of semi-conductor devices, the opening may extend through a conductive cap layer and an appropriate ion bombardment may be established to redistribute material of the underlying metal region to exposed sidewall portions of the conductive cap layer, thereby establishing a protective material. Consequently, in a subsequent wet chemical etch process, the probability for undue material removal of the conductive cap layer may be greatly reduced.
