TSMC Raises Prices On Mature Chips In Single-Digit Increase, Crowding Out STMicroelectronics

TSMC will raise manufacturing prices for mature-process semiconductor chips by a single-digit percentage in the fourth quarter, with new pricing taking effect in January, according to media reports citing unnamed chip design houses.

The pricing adjustment coincides with a shift in production capacity from advanced artificial intelligence processors toward older chips used in power management and microcontrollers. STMicroelectronics is struggling to secure wafer allocations for microcontroller production, prompting a portion of orders to redirect to Chinese foundries.

This is exactly where companies with internal foundries or Chinese foundries will benefit

TSMC plans to hike prices on mature-process chip manufacturing by a single-digit percent in the 4th quarter, media report, citing multiple unnamed chip design houses, with new pricing to take effect in January. Price hikes will vary by cust

RT @Omercheema: This is significant. $STM is the market leader in microcontrollers and they are having problems getting allocations at TSM…

Interesting One of main reasons why orders have been flowing to Chinese foundries

Why it matters: A TSMC mature-node price hike plus capacity shift to AI processors squeezes wafer allocations for microcontroller makers like STMicroelectronics, hurting STM's cost/supply while pushing some orders to Chinese foundries; TSMC gains pricing power.

At publish time: Headline names a specific TSMC mature-chip price increase and explicitly calls out STMicroelectronics being crowded out of wafer allocations — a concrete supply/cost read-through at publish time, not just reaction.

TSMC posted record profit (+77.4%), raised capex, and showed pricing power, confirming TSM:up; but no follow-up evidence of STM being squeezed or crowded out.
