Abstract: A method of manufacturing a pellicle membrane, the method including: providing a first sacrificial layer on a planar substrate to form a stack; and providing, to at least a portion of the stack, at least one metal silicide or doped metal silicide pellicle core layer which forms at least part of the pellicle membrane is described. Also described is a pellicle membrane assembly having a substrate, a first sacrificial layer, and at least one metal silicide or doped metal silicide pellicle layer which forms at least part of a pellicle core, as well as a lithography apparatus including such a pellicle.
