SMIC, China's largest contract chipmaker, raised prices on key chip technologies in direct response to surging demand from artificial intelligence applications. The move confirmed what foundry customers across Asia have been bracing for: the capacity squeeze that started with advanced nodes has migrated decisively into mature-process manufacturing.
Taiwan industry reporting puts this year's price increases at 15 to 20 percent across foundry customers and flags further hikes in 2027. That timeline matters because it signals a multi-year repricing of manufacturing capacity that was previously treated as a commodity.
The specific nodes under pressure include 55 nanometers and above for power devices, 65/55nm silicon interposers and 40/28nm FPGAs, according to TrendForce data. Those are the geometries that show up in everything from industrial controllers to the power-management chips inside AI server racks. The interposer demand in particular is a direct byproduct of AI accelerator packaging, where advanced chips are stitched together using mature-node silicon bridges.
TSMC, the world's largest foundry by revenue, is separately planning price increases of up to 10 percent arriving in Jan. 2027, reports indicate. That TSMC is moving at all is significant: the company already carries a substantial backlog driven by AI customers building custom silicon for data centers. A price hike on top of a backlog signals that management sees no demand relief on the horizon and is optimizing for margin, not market share.
The beneficiaries beyond SMIC are concentrated in Taiwan. UMC, Vanguard International Semiconductor and Powerchip all operate mature-node fabs with rising utilization rates and now face a pricing environment that favors suppliers. Vanguard, which focuses on specialized analog and power processes, and Powerchip, a major DRAM and logic foundry, are positioned for margin expansion as customers compete for limited wafer starts. UMC trades on U.S. markets under the ticker UMC; GlobalFoundries trades as GFS and Skywater Technology as SKYT.
GlobalFoundries, the U.S.-headquartered mature-node foundry, sits in a structurally similar position. It operates exclusively at 12nm and above—exactly the nodes now in demand—and has been expanding capacity in Malta, New York and Singapore. If utilization continues rising and competitors raise prices, GlobalFoundries gains pricing cover to follow.
The economics behind the hike cycle are straightforward. Mature-node fabs were running at low utilization rates as recently as 2023, when the post-pandemic inventory correction gutted demand for consumer electronics. Chipmakers cut prices and in some cases idled lines. AI changed the demand mix faster than capacity could respond. Power semiconductors, silicon interposers and FPGAs became critical AI infrastructure components, and the fabs that make them are now full.
TrendForce projects that AI-driven capacity constraints will keep mature-node prices elevated through 2027—a three-year pricing cycle for what the industry treated as a low-growth, commoditized segment. Customers who signed multi-year supply agreements at pre-hike rates are insulated in the short term; customers on spot or annual renegotiations face the full increase.
Downstream, the price pressure is already reaching consumers. Memory and storage costs have risen as AI demand absorbs supply, and companies including Apple and Microsoft have begun passing those costs through to end-product pricing, according to analyst commentary. The foundry price hike cycle adds another input cost layer on top of memory—one that hits the boards and power circuitry in every device category, not just AI servers.
For SMIC specifically, the price increase carries a strategic dimension beyond margin management. The company operates under U.S. export restrictions that block access to the most advanced lithography equipment, confining it to mature nodes. That constraint, once a ceiling on SMIC's ambitions, is now a commercial advantage: the nodes it can produce are exactly the ones in shortest supply globally. Geopolitical restrictions intended to limit SMIC's competitiveness have inadvertently positioned it at the center of the hottest segment of the foundry market.
The broader foundry pricing cycle is a 2026-2027 story. SMIC moved first. TSMC's increases arrive Jan. 2027. UMC, Vanguard and Powerchip face the same utilization dynamics. The companies buying wafers—power device makers, FPGA suppliers, packaging specialists—are already recalculating product costs. The AI infrastructure buildout that started with GPU shortages has worked its way down the stack to the oldest, most overlooked layer of chip manufacturing.
