Do you expect the rising cost of semiconductor production to lead to higher prices for you?
Market forecasts indicate that the price of silicon wafers will increase significantly by 2027, driven by intense demand for AI-specific components. Projections suggest these material costs will continue to climb through 2028 as supply chain constraints persist.
Why it matters
The surging demand for AI products is placing unprecedented pressure on the raw material supply chain, fundamentally altering the cost structure of semiconductor manufacturing. This bottleneck could dictate the speed and scale at which advanced AI hardware reaches the market over the next three years.
Polished wafer prices are forecast to jump 40% in 2027, while epitaxial wafers—a specialized layer-added wafer type commonly used by TSMC—will see price hikes between 15% and 25%. Industry analysts estimate average wafer prices will reach $122 in 2027, rising to $166 by 2028.
The players
TSMC
The world's largest dedicated independent semiconductor foundry, specializing in advanced process nodes and packaging technologies like CoWoS for AI and high-performance computing clients.
The details
Silicon wafers act as the fundamental base material for semiconductor production, and their processing involves creating high-purity silicon slices that serve as the foundation for complex circuitry. Epitaxial wafers, used extensively in AI supply chains, undergo a process where a thin crystalline layer is deposited onto the base wafer to enhance electrical performance. As demand for GPU and AI ASIC (Application-Specific Integrated Circuit) components grows by 44.9%, manufacturers are signing long-term agreements to secure these critical raw materials.
Timeline
2026: Average wafer prices stood at $92 per unit.
2027: Polished wafer prices are expected to rise by 40%.
2027: CoWoS (Chip-on-Wafer-on-Substrate) production capacity is forecast to increase by 70.9%.
2028: Average silicon wafer prices are estimated to reach $166.
The Tech Race
The semiconductor industry is currently navigating a raw material scarcity caused by the massive expansion in GPU and AI ASIC requirements. This shift follows a pattern where capacity for advanced packaging, such as TSMC's CoWoS, scales aggressively to match the 70.9% production capacity growth target set for 2027.
Rising raw material costs will likely increase the production overhead for manufacturers, which may eventually flow down to higher prices for enterprise and consumer AI hardware. Development timelines may also shift as companies lock in capacity through long-term purchase agreements.
The takeaway
The widening gap between wafer shipments—projected to hit 21.7 million per quarter by 2028—and rising AI demand suggests a sustained, multi-year increase in hardware production costs. Investors and procurement leads should watch quarterly wafer shipment volumes as a leading indicator of supply stability.
