    摘要： Stacked via pillars, such as metal via pillars, are provided at different and designated locations in IC chips to support the chip structure during processing and any related processing stresses such as thermal and mechanical stresses. These stacked via pillars connect and extend from a base substrate of the strip to a top oxide cap of the chip. The primary purpose of the stacked via pillars is to hold the chip structure together to accommodate any radial deformations and also to relieve any stress, thermal and/or mechanical, build-tip during processing or reliability testing. The stacked via pillars are generally not electrically connected to any active lines or vias, however in some embodiments the stacked via pillars can provide an additional function of providing an electrical connection in the chip.

These stacked via pillars connect and extend from a base substrate of the strip to a top oxide cap of the chip. The primary purpose of the stacked via pillars is to hold the chip structure together to accommodate any radial deformations and also to relieve any stress, thermal and/or mechanical, build-up during processing or reliability testing. The stacked via pillars are generally not electrically connected to any active lines or vias, however in some embodiments the stacked via pillars can provide an additional function of providing an electrical connection in the chip.

    摘要： A multilevel semiconductor integrated circuit (IC) structure including a first interconnect level including a layer of dielectric material over a semiconductor substrate, the layer of dielectric material comprising a dense material for passivating semiconductor devices and local interconnects underneath; multiple interconnect layers of dielectric material formed above the layer of dense dielectric material, each layer of dielectric material including at least a layer of low-k dielectric material; and, a set of stacked via-studs in the low-k dielectric material layers, each of said set of stacked via studs interconnecting one or more patterned conductive structures, a conductive structure including a cantilever formed in the low-k dielectric material. The dielectric layer of each of the multiple interconnection levels includes a soft low-k dielectric material, wherein the cantilever and set of stacked via-studs are integrated within the soft low-k dielectric material to increase resistance to thermal fatigue crack formation. In one embodiment, each of the set of stacked via-studs in the low-k dielectric material layers is provided with a cantilever, such that the cantilevers are interwoven by connecting a cantilever on one level to a bulk portion of the conductor line on adjacent levels of interconnection, thereby increasing flexibility of stacked via-studs between interconnection levels.

    摘要： A device, system and method for evaluating reliability of a semiconductor chip are disclosed. Strain is determined at a location of interest in a structure. Failures are evaluated in a plurality of the structures after stress cycling to determine a strain threshold with respect to a feature characteristic. Structures on a chip or chips are evaluated based on the feature characteristic to predict reliability based on the strain threshold and the feature characteristic. Predictions and design changes may be made based on the results.

    摘要： Methods are disclosed for reducing damage to an ultra-low dielectric constant (ULK) dielectric during removal of a planarizing layer such as a crosslinked polymer. The methods at least partially fill an opening with an at most lightly crosslinked polymer, followed by the planarizing layer. When the at most lightly crosslinked polymer and planarizing layer are removed, the at most lightly crosslinked polymer removal is easier than removal of the planarizing layer, i.e., crosslinked polymer, and does not damage the surrounding dielectric compared to removal chemistries used for the crosslinked polymer.
