  • Publication number: 20220317668
    Abstract: A cooling controller receives, from one or more sensors, wafer information associated with a wafer. The cooling controller determines a pattern mask area for the wafer based on the wafer information. The cooling controller determines a cooling time for the wafer based on the pattern mask area. The cooling controller causes a cooling plate to cool the wafer for a time duration equal to the cooling time. Determining the cooling time for a wafer based on a pattern mask area provides stable and consistent wafer temperatures for wafers having different mask and layout properties, which reduces mask overlay variation and increases wafer yield.

  • Publication number: 20220299876
    Abstract: A developer tool described herein includes a dispenser that includes a greater quantity of nozzles in a central portion relative to a perimeter portion such that the developer tool is capable of more effectively removing material from a photoresist layer near a center of a substrate (which tends to be thicker near the center of the substrate relative to the edge or perimeter of the substrate). In this way, the developer tool may reduce the amount of photoresist residue or scum remaining on the substrate near the center of the substrate after a development operation, which may enable defect removal and/or prevention, may increase semiconductor processing yield, and/or may increase semiconductor processing quality.
