ALEXANDRIA, Va., Nov. 6 -- United States Patent no. 12,464,808, issued on Nov. 4, was assigned to Apple Inc. (Cupertino, Calif.).
"Dummy cell designs for nanosheet devices" was invented by Praveen Raghavan (Cupertino, Calif.).
According to the abstract* released by the U.S. Patent & Trademark Office: "Various integrated circuit transistor device structures that implement nanosheet fin transistors are disclosed. Layouts for the transistor device structures include active cells with dummy cells positioned between active cells. The active cells and dummy cells may include nanosheet fin regions that have different widths. In certain instances, the transitions between different nanosheet fin regions widths (e.g., jogs in the widths) are positi...
