  • Publication number: 20240096757
    Abstract: An integrated circuit (IC) die includes first through third adjacent rows of through-silicon vias (TSVs), and first and second adjacent rows of memory macros. TSVs of the first row of TSVs extend through and are electrically isolated from memory macros of the first row of memory macros. TSVs of the third row of TSVs extend through and are electrically isolated from memory macros of the second row of memory macros.

  • Patent number: 9746777
    Abstract: An exposure apparatus includes at least one radiation source, a plurality of projection lenses, and a lens switch. The radiation source is operable for providing a radiation beam. The lens switch is operable for selecting one of the projection lenses to focus the radiation beam to a target plane.

  • Patent number: 7842176
    Abstract: A method for horizontally electroplating or electro deposition a thin film on a substrate comprises the steps of transferring and positioning a substrate on a substrate supporter; the substrate being positioned approximately horizontally; moving a plurality of stop plates to enclose horizontal edges of the substrate so as to form with an enclosure around an edge of the substrate; moving a first electrode to be in contact with a portion of the substrate; the portion being a non-wired area; moving a second electrode to be above and not in contact with the substrate; wherein the second electrode has a polarity opposite to that of the first electrode; and filling electroplating liquid into the enclosure formed by the stop plates so as to be in contact with the second electrode above the substrate for electroplating or electro deposition.
