摘要： A method is provided for removing exposed seed layers in the fabrication of solder interconnects on electronic components such as semiconductor wafers without damaging the interconnects or underlying wafer substrate and with a high wafer yield. The solder interconnects are lead free or substantially lead free and typically contain Sn. An oxalic acid solution is used to contact the wafer after an etching step to remove part of the seed layer. The seed layer is typically a Cu containing layer with a lower barrier layer containing barrier metals such as Ti, Ta and W. The lower barrier layer remains after the etch and the oxalic acid solution inhibits the formation of Sn compounds on the barrier layer surface which compounds may mask the barrier layer and the barrier layer etchant resulting in incomplete barrier layer removal on the wafer surface. Any residual conductive barrier layer can cause shorts and other wafer problems and result in a lower wafer yield. An electroetch is preferred to remove the portion of the seed layer overlying the lower barrier layer.

摘要： An interconnection structure suitable for flip-chip attachment of microelectronic device chips to packages, comprising a two, three or four layer ball-limiting composition including an adhesion/reaction barrier layer, and having a solder wettable layer reactive with components of a tin-containing lead free solder, so that the solderable layer can be totally consumed during soldering, but a barrier layer remains after being placed in contact with the lead free solder during soldering. One or more lead-free solder balls is selectively situated on the solder wetting layer, the lead-free solder balls comprising tin as a predominant component and one or more alloying components.

摘要： A semiconductor device (200) having support structures (218, 226, 236) beneath wirebond regions (214) of contact pads (204) and a method of forming same. Low modulus dielectric layers (216, 222, 232) are disposed over a workpiece (212). Support structures (218, 226, 236) are formed in the low modulus dielectric layers (216, 222, 232), and support vias (224, 234) are formed between the support structures (218, 226, 236). A high modulus dielectric film (220, 230) is disposed between each low modulus dielectric layer (216, 222, 232), and a high modulus dielectric layer (256) is disposed over the top low modulus dielectric layer (232). Contact pads (204) are formed in the high modulus dielectric layer (256). Each support via (234) within the low modulus dielectric layer (232) resides directly above a support via (224) in the underlying low modulus dielectric layer (222), to form a plurality of via support stacks within the low modulus dielectric layers (216, 222, 232).

摘要： Methods are provided that enable the ability to use a less aggressive liner processes, while producing structures known to give a desired high stress migration and electro-migration reliability. The present invention circumvents the issue of sputter damage of low k (on the order of 3.2 or less) dielectric by creating the via “anchors” (interlocked and interpenetrated vias) through chemical means. This allows the elimination or significant reduction of the sputter-etching process used to create the via penetration (“drilling, gouging”) into the line below in the barrier/seed metallization step. The present invention achieves the above, while maintaining a reliable copper fill and device structure.

摘要： A ball-limiting metallurgy includes a substrate, a barrier layer formed over the substrate, an adhesion layer formed over the barrier layer, a first solderable layer formed over the adhesion layer, a diffusion barrier layer formed over the adhesion layer, and a second solderable layer formed over the diffusion barrier layer.

摘要： A first metal is plated onto a substrate comprising a second metal by immersing the substrate into a bath comprising a compound of the first metal and an organic diluent. The second metal is more electropositive than the first metal. The organic diluent has a boiling point higher than a eutectic point in a phase diagram of the first and second metals. The bath is operated above the eutectic point but below the melting point of the second metal. For example, bismuth is immersion plated onto lead-free tin-based solder balls, and subsequently redistributed by fluxless reflow. Plated structures are also provided.

摘要： A copper-interconnect, low-K dielectric integrated circuit has reduced corrosion of the interconnect when the crackstop next to the kerf is also used as the primacy barrier to oxygen diffusion through the dielectric, with corresponding elements of the crackstop being constructed simultaneously with the circuit interconnect elements; e.g. horizontal interconnect elements have a corresponding structure in the crackstop and vias between interconnect layers have corresponding structures in the crackstop.
