    摘要: 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.

    摘要: A structure for a chip or chip package is disclosed, with final passivation and terminal metallurgy which are mechanically decoupled but electrically coupled to the multilayer on-chip interconnects. This decoupling allows the chip to survive packaging stresses in the final passivation region, with strain relief from the decoupling region and compliant leads therein, so that on-chip interconnect levels do not feel these external packaging or other stresses. 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.
