A new take on a centuries-old printing technique could shrink silicon chips and lead to advances in ultra-high-density computer storage.
Computer chips are made by a process called photolithography, in which intricate patterns are etched into silicon wafers at the nanoscale to mark the areas where the insulators, metal tracks and substrates that form the chips are to go. But as the size of electronic components shrinks, this technique is approaching its useful limit: it becomes too costly and difficult to go smaller.
Now Paul Nealey's team at the University of Wisconsin-Madison thinks a new variation on the original lithographic technique could be the answer.
