Smaller microchips

  It's hard to focus the smaller wavelengths of light needed to etch smaller details on microchips. Astronomers use two or more lenses separated by a distance to resolve finer detail, with no change in wavelength. How about using this in reverse, etching chips by using "long baseline interferometry" with current wavelengths.
