  • Patent number: 10689286
    Abstract: A method includes cutting an outer diameter into a glass substrate. An inner diameter within the outer diameter is also cut into the glass substrate. A first region inside the outer diameter and a second region inside the inner diameter are heated. The second region inside the inner diameter is cooled, wherein the cooling causes the second region to detach from the first region.
