  • Patent number: 12199054
    Abstract: A semiconductor device comprises a metallization layer, a passivation layer disposed above the metallization layer, a copper redistribution layer disposed on the passivation layer, a second passivation layer disposed on the copper redistribution layer, and a polyimide layer disposed over the second passivation layer. The polyimide layer and the second passivation layer include a continuous gap there-through that exposes a portion of the copper redistribution layer.
    Type: Grant

  • Patent number: 8683395
    Abstract: Embodiments of the present disclosure disclose a method of forming a new integrated circuit design on a semiconductor wafer using a photolithography tool. The method includes selecting a previously processed wafer having a past integrated circuit design different than the new integrated circuit design, selecting a plurality of critical dimension (CD) data points extracted from the previously processed wafer after the previously processed wafer was etched, and creating a field layout and associated baseline exposure dose map for the new integrated circuit design. The method also includes refining each field in the baseline exposure dose map based on a difference between an average CD for the previously processed wafer and an average CD for each field in the field layout and controlling the exposure of the photolithography tool according to the refined baseline exposure dose map to form the new integrated circuit design on the semiconductor wafer.
