The future of the silicon chip
(Sep 27, 2011)


For more than 40 years, the processing power of the silicon chip has grown in line with a prediction made by Intel co-founder Gordon Moore in 1965. Moore's Law states that the number of transistors that can be placed on a chip for the same cost will double roughly every two years. But researchers know that, at some point, Moore's Law will halt because transistors can get no smaller, so they are looking to nanotechnology to go far beyond the tiny dimensions in current chips.
