  • Publication number: 20190204730
    Abstract: A method for fabricating a pellicle includes forming a first dielectric layer over a back surface of a substrate. After forming the first dielectric layer, and in some embodiments, a graphene layer is formed over a front surface of the substrate. In some examples, after forming the graphene layer, the first dielectric layer is patterned to form an opening in the first dielectric layer that exposes a portion of the back surface of the substrate. Thereafter, while using the patterned first dielectric layer as a mask, an etching process may be performed to the back surface of the substrate to form a pellicle having a pellicle membrane that includes the graphene layer.
