TSMC was the first pure “foundry”, making chips for designers with no factories, or “fabs”, of their own. The doubts of others suited TSMC nicely. Mr Chang, at 82 still chairman and in his second stint as chief executive, says that meant it suffered no competition in its first eight years.These days the idea is more popular. Last year foundries made about half of all logic chips (the ones that carry out computations, as opposed to memory chips, a more commoditised market).

GlobalFoundries, with factories in America, Germany and Singapore, was set up in 2009.Yet the pioneer still dominates.
