Mask Challenges at the 13.5nm wavelength

One of my favorite mask industry analysts is Mark Lapedus at SemiconductorEngineering. In this article, he poses the question: If we solve the EUV source problem, achieve reasonable yields of EUV photoblanks with reflective 40-layer stacks of MoSi, and have a viable pellicle to keep airborne contaminants off the reticle plane, how are we going to inspect these masks?

Maybe Kenneth Goldberg (seen below in what possibly could be the industry's first EUV mask selfie, ca 2011) and his team of SHARP scientists at Berkeley Labs have some ideas:
