    摘要: Methods of forming and the integrated circuit device structure formed having vertical interfaces adjacent an existing crack stop around a perimeter of a chip, whereby the vertical interface controls cracks generated during side processing of the device such as dicing, and in service from penetrating the crack stop. The vertical interface is comprised of a material that prevents cracks from damaging the crack stop by deflecting cracks away from penetrating the crack stop, or by absorbing the generated crack energies. Alternatively, the vertical interface may be a material that allows advancing cracks to lose enough energy such that they become incapable of penetrating the crack stop. The present vertical interfaces can be implemented in a number of ways such as, vertical spacers of release material, vertical trenches of release material or vertical channels of the release material.

    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: The present invention relates to a process for improved interfacial adhesion of dielectrics using patterned roughing. Improved adhesion strength between layers and substrates can be achieved through increasing the roughness of the interface between the materials. Roughness may including any disturbance of an otherwise generally smooth surface, such as grooves, indents, holes, trenches, and/or the like. Roughing on the interface may be achieved by depositing a material on a surface of the substrate to act as a mask and then using an etching process to induce the roughness. The material, acting as a mask, allows etching to occur on a fine, or sub-miniature, scale below the Scale achieved with a conventional photo mask and lithography to achieve the required pattern roughing. Another material is then deposited on the roughened surface of the substrate, filling in the roughing and adhering to the substrate.
