    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.

    Abstract: A reflective mask is described. The mask includes a low thermal expansion material (LTEM) substrate, a conductive layer deposited on a first surface of the LTEM substrate, a stack of reflective multilayers (ML) deposited on a second surface of the LTEM substrate, a capping layer deposited on the stack of reflective ML, a first absorption layer deposited on the first capping layer, a main pattern, and a border ditch. The border ditch reaches to the capping layer, a second absorption layer deposited inside the border ditch, and where the second absorption layer contacts the capping layer. In some instances, the border ditch crosses the capping layer and partially enters the reflective multilayer.
