Polymer nanowires that assemble in perpendicular layers could offer route to tinier chip components

Since the 1960s, computer chips have been built using a process called photolithography. But in the past five years, chip features have gotten smaller than the wavelength of light, which has required some ingenious modifications of photolithographic processes. Keeping up the rate of circuit miniaturization that we've come to expect—as predicted by Moore's Law—will eventually require new manufacturing techniques.
