Abstract: A pellicle comprising a core comprising a material other than silicon carbide, a silicon carbide adhesion layer, and a ruthenium capping layer, the ruthenium capping layer being in contact with the silicon carbide adhesion layer. Also described is a method of preparing a pellicle comprising the steps of: (i) providing a pellicle core; (ii) providing a silicon carbide adhesion layer on the pellicle core; and (iii) providing a ruthenium capping layer in contact with the silicon carbide adhesion layer. Also provided is the use of silicon carbide as an adhesion layer in an EUV pellicle as well as an assembly.
