>Having to use extreme ultraviolet (really soft X-rays) for lithography runs costs way up. EUV "light sources" are insanely complex, involving heating falling droplets of metal to plasma levels with lasers. It's amazing that works as a production technology. The first time a hardware-side friend explained this to me, I was 100% certain he was BSing with hyperbole to emphasize the difficulties involved. Now that I know otherwise, I am still amazed that such a complex method is the easiest one we have. It certainly makes some of my complaints regarding the complexity of software feel trivial!
