ASML Wants to Print Finer Chips. How Far Can the Same Light Go?

High NA is entering real chip production. Its proposed successor would stretch the same extreme-ultraviolet light further—and put the optics under a different kind of pressure.

A two-inch wafer delivered 224 working p-type transistors from a one-atom-thick film—the missing half of ultrathin electronics. Now comes the far harder chip test.
Two semiconductor fabrication test beds will be launched aboard a Falcon 9 rocket, marking a significant step in space-based manufacturing for electronics.
