Researchers are adapting the same methods used in fusion-energy research to create extremely thin plasma beams for a new class of "nanolithography" required to make future computer chips.Current technology uses ultraviolet light to create the fine features in computer chips in a process called photolithography, which involves projecting the image of a mask onto a light-sensitive material, then chemically etching the resulting pattern.New nanolithography will be needed to continue advances in...

U.S. scientists say they're using a fusion-energy research method to create extremely thin plasma beams for a new class of nanolithography. The Purdue University researchers say a new class of nanolithography is needed to make future computer chips We can't make devices much smaller using conventional lithography, so we have to find ways of creating beams having more narrow wavelengths, said Professor Ahmed Hassanein. He said the new plasma-based lithography under development generates...
