(p. 219) Harald Bauer, Jan Veira, and Florian Weig consider “Moore’s Law: Repeal or Renewal?” “Moore’s law states that the number of transistors on integrated circuits doubles every two years, and for the past four decades it has set the pace for progress in the semiconductor industry. . . . Adherence to Moore’s law has led to continuously falling semiconductor prices. Per-bit prices of dynamic random-access memory chips, for example, have fallen by as much as 30 to 35 percent a year for several decades. . . . Some estimates ascribe up to 40 percent of the global productivity growth achieved during the last two decades to the expansion of information and communication technologies made possible by semiconductor performance and cost improvements.” But this continued technological progress comes at an ever-higher price. “A McKinsey analysis shows that moving from 32nm (p. 220) to 22nm nodes on 300-millimeter (mm) wafers causes typical fabrication costs to grow by roughly 40 percent. It also boosts the costs associated with process development by about 45 percent and with chip design by up to 50 percent. These dramatic increases will lead to process-development costs that exceed $1 billion for nodes below 20nm. In addition, the state-of-the art fabs needed to produce them will likely cost $10 billion or more. As a result, the number of companies capable of financing next-generation nodes and fabs will likely dwindle.” McKinsey Global Institute, December 2013, http://www.mckinsey.com/insights/high_tech_telecoms_internet/moores_law_repeal_or_renewal.
