摘要： A method for forming a pellicle for an extreme ultraviolet lithography is provided. The method includes forming a pellicle membrane over a filter membrane and transferring the pellicle membrane from the filter membrane to a membrane border. Forming the pellicle membrane includes growing carbon nanotubes (CNTs) from in-situ formed metal catalyst particles in a first reaction zone of a reactor, each of the CNTs including a metal catalyst particle at a growing tip thereof, growing boron nitride nanotubes (BNNTs) to surround individual CNTs in a second reaction zone of the reactor downstream of the first reaction zone, thereby forming heterostructure nanotubes each including a CNT core and a BNNT shell, and collecting the heterostructure nanotubes on the filter membrane. The metal catalyst particles are partially or completely removed during growing the BNNTs.

摘要： Fabricating a photomask includes forming a protection layer over a substrate. A plurality of multilayers of reflecting films are formed over the protection layer. A capping layer is formed over the plurality of multilayers. An absorption layer is formed over capping layer. A first photoresist layer is formed over portions of absorption layer. Portions of the first photoresist layer and absorption layer are patterned, forming first openings in absorption layer. The first openings expose portions of the capping layer. Remaining portions of first photoresist layer are removed and a second photoresist layer is formed over portions of absorption layer. The second photoresist layer covers at least the first openings. Portions of the absorption layer and capping layer and plurality of multilayer of reflecting films not covered by the second photoresist layer are patterned, forming second openings. The second openings expose portions of protection layer and second photoresist layer is removed.
