Chip manufacturer TSMC sees a declining utilization in 6nm and 7nm processes as people buy fewer smartphones and PCs amid a global economic slowdown. It expects to cut utilization of certain chips in the next three quarters.

Why it matters: The market downturn will not see a recovery in the next six to nine months due to the โ€œgloomy economic outlook,โ€ according to market analysis firm Canalys. Chip contractors like TSMC, which had a high capacity utilization rate, now face vacancies in certain tech nodes.

  • Such issues could worsen the situation for TSMC, which is already facing the loss of orders from mainland China due to the latest US chip export controls. For example, Birenโ€™s BR100 GPU has adopted TSMCโ€™s 7nm process, but the chipmaker has put its work with the firm on hold due to the ban.
  • In more positive news, the development could help to relieve chip shortages in other fields such as gaming consoles. Steam Deck, Xbox Series X, and Playstation 5 all use AMD customized processors built with TSMCโ€™s 7nm tech.

Details: TSMC released its financial results for the third quarter of this year on Oct. 13 and gave conservative guidance of 0.4% quarterly revenue growth for the next quarter. The company also said its 6nm and 7nm production could remain affected until next year.

  • C. C. Wei, TSMCโ€™s CEO of the firm, stated that the firmโ€™s 7nm production capacity utilization was affected as a result of the weak demands of personal computers and smartphones and semiconductor inventory adjustments, which will be relieved in the second half of 2023.
  • 6nm and 7nm nodes comprised 26% of TSMCโ€™s revenues in the third quarter of 2022, according to a report from Counterpoint. Smartphones and high-performance computing (HPC) devices, like CPU and GPU for PCs and servers, made up 32% and 38% of TSMCโ€™s total wafer shipment volume in 2022, respectively.
  • The report also pointed out that โ€œthe global foundry industryโ€™s utilization rate has reached its peak level in mid-2022 [and] the downtick will bring down business in all aspects in the next few quarters before any signs of improvement emerge in inventory levels across the semiconductor supply chain.โ€ย 
  • TSMCโ€™s utilization rate of 6nm and 7nm could drop to 80% to 90% in the next three quarters, and it would be unlikely to recover until clients such as Intel deliver more orders.
  • Counterpointโ€™s report does however agree with TSMC that there could be โ€œpositive driversโ€ via new products such as Wi-Fi, radio-frequency (RF), and solid-state drive controller chips migrating onto 6nm or 7nm when the inventory cycle ends in 2023.

Context: TSMC is a top chipmaker worldwide, dominating 56% of the market by revenue in the second quarter of this year, according to Counterpoint. The chipmaker generated a revenue of $20.23 billion for the third quarter this year, a yearly growth rate of 35.9%.

  • 7nm and 6nm are important tech nodes, contributing 17% of the global chip foundry revenues in the second quarter of 2022.
