Abstract: A wafer including a mask on one face and at least one layer on an opposite face, wherein the mask has at least one scribeline which overlies at least a portion of the opposite face which is substantially free of the at least one layer is described. Also described is a method of preparing a pellicle, the method including: providing a wafer having a mask on one face and at least one layer on an opposite face, defining a scribeline in the mask, and selectively removing a portion of the at least one layer which at least partially overlies the scribeline as well as a method of preparing a pellicle, the method including: providing a pellicle core, and removing at least some material from at least one face of the pellicle core in a non-oxidizing environment. In any aspect, the pellicle may include a metal nitride layer.

Abstract: A first diffusor configured to receive and transmit radiation has a plurality of layers, each layer arranged to change an angular distribution of EUV radiation passing through it differently. A second diffusor configured to receive and transmit radiation has a first layer and a second layer. The first layer is formed from a first material, the first layer including a nanostructure on at least one surface of the first layer. The second layer is formed from a second material adjacent to the at least one surface of the first layer such that the second layer also includes a nanostructure. The second material has a refractive index that is different to a refractive index of the first layer. The diffusors may be configured to receive and transmit EUV radiation.

Abstract: Membranes for EUV lithography are disclosed. In one arrangement, a membrane has a stack having layers in the following order: a first capping layer including an oxide of a first metal; a base layer including a compound having a second metal and an additional element selected from the group consisting of Si, B, C and N; and a second capping layer including an oxide of a third metal, wherein the first metal is different from the second metal and the third metal is the same as or different from the first metal.
