TOKYO/SINGAPORE/AMSTERDAM, Sept 15 (Reuters) - Taiwan's TSMC 2330.TW has told its major suppliers to delay the delivery of high-end chipmaking equipment, as the world's top contract chipmaker grows increasingly 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 as the information is public.
TSMC said it does comment on "market rumour".
The company referred Reuters to comments by CEO C.C. Wei in July that weaker economic conditions, slower recovery in China and softer end-market demand is making customers more cautious and more mindful of controlling inventory.
Companies affected by the instruction to delay include Dutch firm ASML ASML.AS, which makes lithography equipment essential for high-end chipmaking, the sources said.
In an interview with Reuters last week, ASML CEO Peter Wennink said some orders for its high-end tools have been pushed back, without customers, and that he expected it would be a "short-term management" issue.
ASML is operating at maximum capacity and overall sales are forecast to grow 30% this year.
"We've had several () reports about fab readiness. Not only in Arizona ... but also in Taiwan," Wennink told Reuters, referring to preparations for chip manufacturing.
TSMC has been forced toat the Arizona plant by a year to 2025, as it struggled to recruit workers and faced pushback from unions on efforts to bring in workers from Taiwan.
"If you ship a lot of people from Taiwan to help build a factory in Arizona, they're working somewhere else. So this is kind of a double whammy," Wennink said.
TSMC Chairman Mark Liu said last week there had been "tremendous" improvement at the Arizona site in the last five months.
CHIP CYCLE WORRIES
The Taiwanese chip giant is alone in worrying a bounce back in demand may take longer than expected.
Apple, a key TSMC customer, launched athis week that included a faster chip, but it did raise prices, reflecting the global smartphone slump.
Media reports that Beijing has ordered some government employees toat work, and the launch by tech firm Huawei of a flagship phone using Chinese-made chips, is causing further unease at TSMC, one of the sources said.
TSMC used to make chips for Huawei but suspended supplies after Washington imposed sanctions on the Chinese firm. Analysts have found Huawei worked with Chinese contract chipmaker Semiconductor Manufacturing International Corp (SMIC) 0981.HK to manufacture an advanced chip for its latest smartphone.
TSMC forecast in July a 10% slide in 2023 sales and as much as a 4% point drop in operating margin this quarter from the previous quarter, citing weak demand for smartphones and PCs and uncertainty about the market for artificial intelligence.
The chipmaker is also facing elevated capital expenditure, which increased 21% to $36 billion last year, from expansion plans put in place during the pandemic-driven chips boom.
Itthat investment spending for this year would be at the lower end of a previous forecast of $32 billion to $36 billion, and said it expected a slower increase in the few years.
