Silicon wafers rise again: Taiwan advances another increase in chip prices

The recovery of the silicon wafer market is starting to impact prices. After nearly two years of inventory adjustments, three Taiwanese manufacturers—Wafer Works, Taisil, and GlobalWafers—have announced new price increases across different product lines. The movement initially affects 6-inch wafers, where increases have already been completed in some cases, but it is also beginning to spread to 8- and 12-inch wafers, the two categories with the greatest industrial impact.

The message is clear: the semiconductor supply chain has moved out of its weakest phase and is regaining pricing power. Demand for artificial intelligence continues to drive advanced nodes, while mature processes are rebounding due to automotive, industrial electronics, power management, MEMS, and analog circuits. At the same time, energy, transportation, and raw materials are still exerting cost pressures.

Not all wafers serve the same purposes. 12-inch, or 300 mm, wafers dominate advanced manufacturing and a significant portion of high-volume chip production. 8-inch, or 200 mm, wafers remain essential for power management, automotive, sensors, analog, and many semiconductors that do not require the most advanced nodes. Older 6-inch wafers continue to have importance in power devices, MEMS, and mature applications where switching processes may not be cost-effective to replace.

Recovery Is No Longer Just About AI

Throughout much of 2024 and 2025, the wafer market experienced uneven recovery. AI sustained demand for advanced logic, memory, and HBM, but other sectors like PCs, smartphones, automotive, and industry were still adjusting inventories. Now, the rebound is becoming broader, though still not uniform.

SEMI reported that global silicon wafer shipments grew 13.1% year-over-year in the first quarter of 2026, reaching 3.275 billion square inches, compared to 2.896 billion in the same period of 2025. The organization attributed this growth both to demand from AI data centers, advanced logic, and memory, as well as a broader recovery in industrial semiconductors and power management devices.

The key point is that the recovery is not limited to the most advanced chips. Many sectors depend on mature processes. An electric vehicle, an automated factory, or a power supply system require hundreds or thousands of components that do not need 2 or 3-nanometer nodes. They need availability, reliability, reasonable costs, and supply continuity.

Wafer Works: 6-inch Wafers Are Already Tight

Wafer Works has indicated that it completed price adjustments for 6-inch wafers earlier this year and now observes a market where demand surpasses supply. This isn’t solely due to AI. The company points out that some international suppliers, including SUMCO and Siltronic, have reduced or exited some 6-inch production lines, tightening available capacity.

This is important because it shows how a seemingly mature market can become strained without major headlines. If manufacturers shift investments toward 12-inch or higher-margin products, older lines may see diminished capacity at a time when sectors like power, MEMS, industrial, and energy management continue to demand steady supply.

Wafer Works maintains a broad customer base in mature processes, especially power devices, PMICs, and MEMS. For the company, keeping these lines operational could be more efficient than it seems, as supply has tightened and customers require continuity.

The company also sees room for further price increases in 8-inch wafers during the second half of the year. The boost is driven not only by power management devices but also by the broader power semiconductor market, including automotive, industrial control, and energy management applications.

Taisil: Full Capacity in 8 and 12 Inches

Taisil has reported that its 8- and 12-inch lines are operating at full capacity. Demand in 8-inch wafers has heated up enough that many customers are already discussing additional orders for the second half of 2026 and requirements for 2027. This kind of forward planning is a classic sign of a cycle change: when buyers fear future shortages, they tend to lock in capacity earlier.

The company believes that 8-inch wafers have margin for price increases. Regarding 12-inch wafers, Taisil is already negotiating a new pricing adjustment mechanism with clients for the second half, although the price hikes customers are prepared to accept are still below the company’s expectations.

This tug-of-war is normal. Wafer manufacturers want to pass through costs and regain margins. Customers, who produce chips for third-party or end-product manufacturers, try to contain the impact because they cannot always pass on costs immediately. The difference now is that, in a recovering market, suppliers have greater capacity to negotiate.

GlobalWafers: Uneven Recovery, but More Clear

GlobalWafers, one of the industry’s major global players, describes 2026 as an ascending yet uneven recovery. Demand driven by AI and advanced processes remains strong, while markets not directly linked to AI, such as automotive and industrial sectors, are beginning to improve.

The company had already indicated in May that it was considering price hikes from the second half of the year to reflect higher energy, transportation, raw material costs, and depreciation tied to new factories. It also reported high utilization rates on 12-inch facilities and some smaller plants in Taiwan, Malaysia, and China.

GlobalWafers is also preparing to expand its Texas plant, its most advanced 300 mm wafer facility in the United States, provided it secures customer commitments. This move aligns with a broader trend: wafers are becoming a strategic component of industrial policy, no longer just an input in the supply chain.

Why a Wafer Price Increase Matters to Consumers

Silicon wafers are the starting point of chips. Transistors, memory, sensors, processors, controllers, and power components are all built on them. When wafer prices rise, it does not necessarily mean that a mobile phone, car, or laptop will automatically become more expensive in the same proportion. However, it does increase pressure along the entire supply chain.

Chip manufacturers might absorb some costs, pass them on to customers, adjust margins, renegotiate contracts, or prioritize higher-margin products. In tense markets, a mix of all these strategies is common. The result can manifest months later in component prices, delivery times, part availability, or end-product costs.

The impact can be especially visible in sectors that rely on mature processes. The chip shortages during the pandemic already demonstrated that not everything depends on the most advanced nodes. A vehicle may be delayed because of a mature microcontroller or an 8-inch power chip. A factory might postpone equipment orders due to sensors or industrial components that do not headline news but are vital for operations.

The Cycle Returns, But with a Different Composition

The wafer industry has always been cyclical. When demand declines, inventories rise, customers cut orders, and suppliers lose pricing power. When demand recovers and capacity is adjusted, prices tend to rise again. What has changed now is the composition of this cycle.

AI drives demand from above, for 12-inch wafers, advanced memory, HBM, logic, and data centers. But the rebound in 6- and 8-inch wafers shows that recovery is also reaching less visible parts of the digital economy. Power, industrial control, automotive, and energy management are highly physical areas tied to electrification, factories, infrastructure, and connected devices.

This new equilibrium may favor manufacturers with flexible capacity, diverse customer bases, and exposure to both advanced nodes and mature processes. It could also leave behind those who shut down old lines too early or rely on a single segment.

An Early Signal for the Entire Chip Supply Chain

The signals from Wafer Works, Taisil, and GlobalWafers are not just local to Taiwan. Taiwan is a central player in the global semiconductor supply chain, and changes by its suppliers often anticipate cost and capacity shifts experienced downstream by foundries, component manufacturers, and end customers.

For TSMC, UMC, VIS, Powerchip, and other manufacturers, wafer costs and availability form part of a complex equation alongside energy, chemicals, equipment, talent, depreciation, and customer demand. Chip designers may face higher contracts or less flexibility due to upstream pressures. Electronics manufacturers could see added costs, especially as memory, storage, and advanced packaging costs also rise.

The wafer market is sending a clear signal: the era of abundant inventory and weak prices is beginning to end. Not all segments are equally strong, but bargaining power is shifting back toward suppliers. In an industry obsessed with AI, this recovery of mature processes emphasizes a fundamental point: the digital world also depends on modest chips, older wafers, and factories that do not make the headlines of the biggest models.
