    Abstract: A method for reducing wiggling in a line includes forming a silicon patterning layer over a substrate and depositing a mask layer over the silicon patterning layer. The mask layer is patterned to form one or more openings therein. The mask layer is thinned and the one or more openings are widened, to provide a smaller height-to-width ratio. The pattern of the mask layer is then used to pattern the silicon patterning layer. The silicon patterning layer is used, in turn, to pattern a target layer where a metal line will be formed.

  • Publication number: 20190054525
    Abstract: A liquid composition includes copper particles, an organic acid, and a solvent. The copper particle has a particle size of 0.5 ?m˜30 ?m which falls in a micron scale. The liquid composition performs reaction sintering by redox reactions taken place between the copper particles and an organic acid solution at a low temperature of 150° C. in order to produce a dense copper layer and improve the conventional micron-scale copper particles that requires a protective atmosphere for the high-temperature sintering before achieving the required densification. This liquid composition also prevents an excessive oxidation of the nano copper particles during the low-temperature sintering process and a failure of the dense sintering. Due to the agglomeration of nano copper particles, some areas have to be sintered first, so that the sintered products have a good uniformity of tissue and a low resistance below 0.04 ohm per square (?/?).

  • Patent number: 10163688
    Abstract: Among other things, one or more interconnect structures and techniques for forming such interconnect structures within integrated circuits are provided. An interconnect structure comprises one or more kinked structures, such as metal structures or via structures, formed according to a kinked profile. For example, the interconnect structure comprises a first kinked structure having a first tapered portion and a second kinked structure having a second tapered portion. The first tapered portion and the second tapered portion are both situated at an interface between two layers. Current leakage at the interface is mitigated because a length of the interface corresponds to a distance between the first tapered portion and the second tapered portion that is relatively larger than if the first kinked structure and the second kinked structure were merely formed according to a non-tapered shape.
