Many requirements of a point-source x-ray membrane mask are different than for a synchrotron source. Membranes must be thinner, flatter and stronger, for example. We characterize our polysilicon and silicon-rich nitride membranes, and a simplified one-piece (monolithic) mask blank. We use two strength testing techniques which discern whether membrane strength is limited by defects in the film growth process, or defects in the attachment of membrane to support We find our membrane films are stronger than previously thought, and that improvements in membrane/support attachment will effect a more durable membrane mask.
