  • Publication number: 20240363561
    Abstract: A method includes forming a seed layer on a semiconductor wafer, coating a photo resist on the seed layer, performing a photo lithography process to expose the photo resist, and developing the photo resist to form an opening in the photo resist. The seed layer is exposed, and the opening includes a first opening of a metal pad and a second opening of a metal line connected to the first opening. At a joining point of the first opening and the second opening, a third opening of a metal patch is formed, so that all angles of the opening and adjacent to the first opening are greater than 90 degrees. The method further includes plating the metal pad, the metal line, and the metal patch in the opening in the photo resist, removing the photo resist, and etching the seed layer to leave the metal pad, the metal line and the metal patch.
