The Multiple Lives of Moore’s Law - IEEE Spectrum via @IEEESpectrum by "Gentleman scientist” Chris Mack

If lithography costs rise fast, Moore’s Law as we know it will come to a quick halt. And there are signs that the end could come quite soon. Today’s advanced chips are made with immersion lithography, which makes patterns by exposing water-immersed wafers to 193-nm, deep ultraviolet light. The planned successor is lithography using shorter-wavelength, extreme ultraviolet light. That technology was supposed to come on line as early as 2004. But it’s suffered delay after delay, so chipmakers have had to turn to stopgaps such as double patterning , which doubles up some steps to fashion the finest features. Double patterning takes twice as long as single patterning. Nonetheless, chipmakers are contemplating triple and even quadruple patterning, which will further drive up costs. A few years from now, we may look back on 2015 as the year the tide turned and the cost of transis...
