Abstract:
A method for manufacturing a pellicle includes: providing a supporting substrate; forming an oxide layer over the supporting substrate; forming a metal layer over the oxide layer; forming a graphene layer over the metal layer; and removing at least a portion of the supporting substrate and the oxide layer. An associated method includes: providing a supporting substrate; forming a first silicon carbide (SiC) layer or a diamond layer over the supporting substrate; forming a graphene layer over the SiC layer or the diamond layer; and removing at least a portion of the supporting substrate and the first silicon carbide (SiC) layer or the diamond layer; wherein the pellicle is at least partially transparent to extreme ultraviolet (EUV) radiation. An associated pellicle is also disclosed.
