Taiwan's TSMC has told its major suppliers to delay the delivery of high-end chipmaking equipment, as the world's top contract chipmaker grows increasingly nervous about customer demand, two sources familiar with the matter said. The instruction by TSMC, which is grappling with delays at its $40 billion chip factory in Arizona, is aimed at controlling costs and reflects the company's growing caution about the outlook for demand, the sources said. Suppliers currently expect the delay to be short-term, the sources said, declining to be named as the information is not public. TSMC said it does not comment on "market rumour"....
