    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 scribe line structure of a semiconductor wafer is provided in the invention. The semiconductor wafer has a plurality of substantially parallel horizontal scribe lines and a plurality of substantially parallel vertical scribe lines to separate a plurality of chips from each other. According to the invention, each parallel horizontal scribe line and each parallel vertical scribe line are divided along two elongated sides thereof into a plurality of portions with the same rectangular area. Each of the plurality of portions of each scribe line is composed of the scribe line structure. The scribe line structure comprises a multi-layer structure with four sides formed over whole area of each portion of each scribe line and at least two rows of cavities formed along the four sides of the multi-layer structure. The cavities of the scribe line structure are capable of relieving internal stress of the scribe lines and arresting possible cracks induced during scribe line manufacture. Thereby, peeling, delamination and dielectric fracture of the scribe lines induced during the wafer manufacture can be prevented.

    摘要： A process for forming shallow trench isolation (STI) structures. It includes the steps of: (a) depositing a composite silicon nitride on to the silicon substrate; (b) forming a shallow trench on the silicon substrate by etching, using the composite silicon nitride as the hard mask; (c) depositing a filler oxide layer inside the shallow trench as well as on top of the composite silicon nitride, using a chemical vapor deposition (CVD) method; and (d) using a chemical-mechanical polishing (CMP) process to planarize the filler oxide layer using the composite nitride as a CMP stop. The composite silicon nitride comprises a plurality of silicon nitride layers whose CMP removal rate increases with the distance from the silicon substrate. Additionally, a composite silicon oxide layer can be formed on top of the filler oxide layer which comprises a plurality of silicon oxide layers whose CMP removal rate increases with the distance from the silicon substrate.
