摘要： Different ways to reduce or eliminate the IMC cracking issues in wire bonded parts, including: changing to more compressive dielectric films for top, R1, and R2; changing the top passivation film stacks to more compressive films; changing the low k film to a higher compressive film; reducing the R layer thickness and pattern density to reduce tensile stress; and minimizing anneal and dielectric deposition temperatures. Each of the methods can be used individually or in combination with each other to reduce overall tensile stresses in the Cu/low-k wafer thus reducing or eliminating the IMC cracking issue currently seen in the post wire bonded parts.

摘要： A pad structure and passivation scheme which reduces or eliminates IMC cracking in post wire bonded dies during Cu/Low-K BEOL processing. A thick 120 nm barrier layer can be provided between a 1.2 μm aluminum layer and copper. Another possibility is to effectively split up the barrier layer, where the aluminum layer is disposed between the two barrier layers. The barrier layers may be 60 nm while the aluminum layer which is disposed between the barrier layers may be 0.6 μm. Another possibility is provide an extra 0.6 μm aluminum layer on the top barrier layer. Still another possibility is to provide an extra barrier layer on the top-most aluminum layer, such that a top barrier layer of 60 nm is provided on a 0.6 μm aluminum layer, followed by another barrier layer of 60 nm, another aluminum layer of 0.6 μm and another barrier layer of 60 nm.

摘要： A bond pad structure which includes an aluminum bond pad which include one or more dopants that effectively control the growth of IMC to a nominal level in spite of high tensile stresses in the wafer. For example, aluminum can be doped with 1–2 atomic % of Mg. Alternatively, Pd or Si can be used, or elements like Cu or Si can be used as the dopant in order to reduce the overall tensile stresses in the wafer. This can control the abnormal growth of IMC, thus arresting the IMC crack formation. A combination of dopants can be used to both control the tensile stresses and also slightly alter the gold-Aluminum interface thus enabling a uniform and thin IMC formation. This tends to reduce or eliminate any voiding or cracking which would otherwise occur at the wire bond transfer.

摘要： Passivation integration schemes and pad structures to reduce the stress gradients and/or improve the contact surface existing between the Al in the pad and the gold wire bond. One of the pad structures provides a plurality of recessed pad areas which are formed in a single aluminum pad. An oxide mesa can be provided under the aluminum pad. Another pad structure provides a single recessed pad area which is formed in a single aluminum pad, and the aluminum pad is disposed above a copper pad and a plurality of trench/via pads. Still another pad structure provides a single recessed pad area which is formed in a single aluminum pad, and the aluminum pad is disposed above a portion of a copper pad, such that the aluminum pad and the copper pad are staggered relative to each other.

摘要： A metal layer formed on a semiconductor wafer is planarized by applying sequentially a deplating step, a plating step, and a relaxation step in a removal cycle. A series of cycles are performed sequentially in one embodiment to comprise a pass. The removal cycle is repeated in sequence until the pass is completed. The respective deplating and plating rates are adjusted so that the ratios of deplating rates to plating rates progressively decrease from an initial pass to a final pass. Organic additives are added to the electrolytic plating solution to control the plating portion of the cycle in a topography dependant fashion.

摘要： A method for restoring an eroded portion in an exposed upper surface cavity of a metallic element in a microelectronic device, where the metallic element has a hardness, and the metallic element is laterally surrounded by lateral elements, where at least one structure within the lateral elements has a hardness that is greater than the hardness of the metallic element. A precursor material is deposited in at least the cavity of the upper surface of the metallic element. The precursor material is deposited to a thickness that at least fills the cavity of the upper surface of the metallic element. The precursor material has a hardness that is less than the hardness of the at least one structure within the lateral elements. The precursor material is removed as necessary from the lateral elements, and the precursor material is planarized. Only the precursor material within the cavity of the upper surface of the metallic element is selectively replaced with a desired material. The eroded portion of the metallic element is thereby restored. By removing precursor material from those areas in which no replacement with the desired material is wanted, the desired material is selectively deposited only in those place where the precursor material remains, and where it is desired to fill in the cavities or dishing that was created in the areas of the softer metallic elements between the harder laterally surrounding elements during a prior chemical mechanical polishing process. Thus, the microelectronic device is more fully planarized, as the dishing is filled in, and the metallic element is supplemented with an additional amount of desired material.

摘要： An arrangement for polishing a semiconductor wafer is disclosed. The arrangement includes a plurality of preassembled polishing pad assemblies which can be selectively coupled to, and decoupled from, an actuating mechanism for rotating the polishing pad assemblies. An associated method of polishing a semiconductor wafer is also disclosed.
