Abstract: Methods of manufacturing a membrane assembly where, in one arrangement, a stack includes a planar substrate and at least one membrane layer. The planar substrate includes an inner region, a border region around the inner region, a bridge region around the border region and an edge region around the bridge region. The inner region and a first portion of the bridge region are removed. The membrane assembly after removal has: a membrane formed from the at least one membrane layer, a border holding the membrane, the border formed from the border region, an edge section around the border, the edge section formed from the edge region, a bridge between the border and the edge section, the bridge formed from the at least one membrane layer and a second portion of the bridge region. The method further involves separating the edge section from the border by cutting or breaking the bridge.

Abstract: A method of manufacturing a membrane assembly for EUV lithography, wherein a layer which forms at least part of a pellicle membrane is provided after one or more etching steps which define a pellicle border holding the pellicle membrane. Also provided is a pellicle substrate, the substrate including: a stack having a front face and back face, wherein one or more layers on the back face of the stack have been selectively removed to define a pellicle border region for holding the pellicle membrane before the layer which forms at least part of a pellicle membrane has been provided.

Abstract: A method comprising the steps of receiving a mask assembly comprising a mask and a removable EUV transparent pellicle held by a pellicle frame, removing the pellicle frame and EUV transparent pellicle from the mask, using an inspection tool to inspect the mask pattern on the mask, and subsequently attaching to the mask an EUV transparent pellicle held by a pellicle frame. The method may also comprise the following steps: after removing the pellicle frame and EUV transparent pellicle from the mask, attaching to the mask an alternative pellicle frame holding an alternative pellicle formed from a material which is substantially transparent to an inspection beam of the inspection tool; and after using an inspection tool to inspect the mask pattern on the mask, removing the alternative pellicle held by the alternative pellicle frame from the mask in order to attach to the mask the EUV transparent pellicle held by the pellicle frame.

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.

Abstract: A diagnostic apparatus monitors a lithographic manufacturing system. First measurement data representing local deviations of some characteristic across a substrate is obtained using sensors within a lithographic apparatus, and/or a separate metrology tool. Other inspection tools perform substrate backside inspection to produce second measurement data. A high-resolution backside defect image is processed into a form in which it can be compared with lower resolution information from the first measurement data. Cross-correlation is performed to identify which of the observed defects are correlated spatially with the deviations represented in the first measurement data. A correlation map is used to identify potentially relevant clusters of defects in the more detailed original defect map. The responsible apparatus can be identified by pattern recognition as part of an automated root cause analysis. Alternatively, reticle inspection data may be used as second measurement data.
