Abstract: An assembly for a lithographic apparatus, wherein the assembly is configured to heat a pellicle membrane by one of or a combination selected from: i) provision of heated gas, ii) radiative heating, iii) resistive heating, and/or iv) inductive heating, and/or by illuminating the pellicle membrane with light having a wavelength of from around 91 nm to around 590 nm. Also a method of extending the operative lifespan of a pellicle membrane, the method including heating at least a portion of a pellicle membrane when illuminated by EUV by one of or a combination selected from: i) providing heated gas, ii) radiative heating, iii) resistive heating, and/or iv) inductive heating to effect heating of the at least one portion of the pellicle membrane, and/or by illuminating the pellicle membrane with light having a wavelength of from around 91 nm to around 590 nm.
