  • Publication number: 20240118464
    Abstract: An apparatus is disclosed which includes an ultraviolet laser and at least one reflective mirror having a substrate which is made from beryllium, an aluminum metal matrix, or silicon carbide. The at least one mirror is adapted to reflect a laser beam generated from the ultraviolet laser, which can then be used on a silicon film used in the production of an electronic display. The laser beam can be used to anneal the silicon film, or in a laser lift-off process for separating the silicon film from a temporary substrate upon which the silicon film was mounted.
