    摘要: Deep trenches formed beneath contact level in a semiconductor substrate function as crackstops, in a die area or in a scribe area of the wafer, and may be disposed in rows of increasing distance from a device which they are intended to protect, and may be located under a lattice work crackstop structure in an interconnect stack layer. The deep trenches may remain unfilled, or may be filled with a dielectric material or conductor. The deep trenches may have a depth into the substrate of approximately 1 micron to 100 microns, and a width of approximately 10 nm to 10 microns.

    摘要: The present invention provides a method for forming a low-k dielectric structure on a substrate 10 that includes depositing, upon the substrate, a dielectric layer 12. A multi-film cap layer 18 is deposited upon the dielectric layer. The multi-film cap layer includes first 181 and second 182 films, with the second film being disposed between the dielectric layer and the first film. The first film typically has a removal rate associated therewith that is less than the removal rate associated with the second film. A deposition layer 20 is deposited upon the multi-film cap layer and subsequently removed. The properties of the multi-film cap layer are selected so as to prevent the dielectric layer from being exposed/removed during removal of the deposition film. In this manner, a deposition layer, having variable rates of removal, such as copper, may be planarized without damaging the underlying dielectric layer.

    摘要: A microelectronic element, e.g., a semiconductor chip having a silicon-on-insulator layer (“SOI layer”) separated from a bulk monocrystalline silicon layer by a buried oxide (BOX) layer in which a crack stop extends in first lateral directions at least generally parallel to the edges of the chip to define a ring-like barrier separating an active portion of the chip inside the barrier with a peripheral portion of the chip. The crack stop can include a first crack stop ring contacting a silicon portion of the chip above the BOX layer; the first crack stop ring may extend continuously in the first lateral directions to surround the active portion of the chip. A guard ring (“GR”) including a GR contact ring can extend downwardly through the SOI layer and the BOX layer to conductively contact the bulk monocrystalline silicon region, the GR contact ring extending at least generally parallel to the first crack stop ring to surround the active portion of the chip. A continuous metal ring extending continuously in the first lateral directions can surround the active portion of the chip, such metal ring connecting the GR contact ring with the first crack stop ring such that the metal line and the GR contact ring form a continuous seal preventing mobile ions from moving between the peripheral and active portions of the chip.

    摘要: A method for integrating cap liner formation in back-end-of-line (BEOL) processing of a semiconductor device includes forming a trench structure within an insulating layer of the semiconductor device, depositing a first liner material over a top surface of the insulating layer, including sidewall and bottom surfaces of the trench, and partially filling the trench with a wiring metal material to a height corresponding to a final intended line height. A second liner material is over the wiring metal material, and a sacrificial fill material is formed over the second liner material. The sacrificial fill is planarized down to the level of the second liner material over the wiring metal material partially filling the trench, wherein a remaining portion of the second liner material defines a cap liner of the wiring metal.
