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.

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.
