This structure is particularly preferred for on-chip interconnects consisting of Cu and low-k dielectric, the latter having inferior mechanical properties relative to SiO2. The decoupled region extends over all chips on the wafer. It may also extend into the edgeseal or dicing channel region so as to allow chip dicing and retention of this mechanical decoupling all around every chip on the wafer.

  • Patent number: 7087982
    Abstract: Dielectric compositions comprised of porous polymeric matrices are prepared using nitrogen-containing polymers as pore-generating agents. The compositions are useful in the manufacture of electronic devices such as integrated circuit devices and integrated circuit packaging devices. The dielectric compositions are prepared by admixing a polymeric nitrogenous porogen with a high temperature, thermosetting host polymer in a suitable solvent, heating the admixture to cure the polymer and provide a vitrified matrix, and then decomposing the porogen using heat, radiation, or a chemical reagent effective to degrade the porogen. The highly porous dielectric materials so prepared have an exceptionally low dielectric constant on the order of 2.5 or less, preferably less than about 2.0. Integrated circuit devices and integrated circuit packaging devices manufactured so as to contain the dielectric material of the invention are provided as well.

  • Patent number: 7071539
    Abstract: An electrical interconnect structure on a substrate, which includes: a first low-k dielectric layer; a spin-on low k CMP protective layer that is covalently bonded to the first low-k dielectric layer; and a CVD deposited hardmask/CMP polish stop layer is provided. Electrical vias and lines can be formed in the first low k dielectric layer. The spin-on low k CMP protective layer prevents damage to the low k dielectric which can be created due to non-uniformity in the CMP process from center to edge or in areas of varying metal density. The thickness of the low-k CMP protective layer can be adjusted to accommodate larger variations in the CMP process without significantly impacting the effective dielectric constant of the structure.
