  • Patent number: 11773506
    Abstract: An IC fabrication system for facilitating improved thermal uniformity includes a chamber within which an IC process is performed on a substrate, a heating mechanism configured to heat the substrate, and a substrate-retaining device configured to retain the substrate in the chamber. The substrate-retaining device includes a contact surface configured to contact an edge of the retained substrate without the substrate-retaining device contacting a circumferential surface of the retained substrate. The substrate-retaining device includes a plurality of contact regions and a plurality of noncontact regions disposed at a perimeter, where the plurality of noncontact regions is interspersed with the plurality of contact regions. Each of the plurality of noncontact regions includes the contact surface.

  • Patent number: 9647066
    Abstract: A FinFET device may include a dummy FinFET structure laterally adjacent an active FinFET structure to reduce stress imbalance and the effects of stress imbalance on the active FinFET structure. The FinFET device comprises an active FinFET comprising a plurality of semiconductor fins, and a dummy FinFET comprising a plurality of semiconductor fins. The active FinFET and the dummy FinFET are laterally spaced from each other by a spacing that is related to the fin pitch of the active FinFET.

  • Patent number: 9517539
    Abstract: A substrate-retaining device with improved thermal uniformity is provided. In an exemplary embodiment, the substrate-retaining device includes a substantially circular first surface with a defined perimeter, a plurality of contact regions disposed at the perimeter, and a plurality of noncontact regions also disposed at the perimeter. The contact regions are interspersed with the noncontact regions. Within each of the noncontact regions, the first surface extends past where the first surface ends within each of the contact regions. In some such embodiments, each region of the plurality of contact regions includes a contact surface disposed above the first surface.
