China can make advanced chips without EUV, but the bill keeps growing — DUV multiple patterning means bigger dies, lower yields, and longer manufacturing times
China has stretched older DUV lithography far further than expected, using multiple patterning to approach 5nm-class without EUV. But experts say the trade-offs in cost, yield, and die size mean further advancements are unlikely to be economically viable.
Birds can see ultraviolet light, in addition to the colors that the human eye can see. These groundbreaking photos by Nathan Chronister give us a first glimpse of what birds might look like to other birds.
