Semiconductor Material Prices Rise as Petrochemical Costs Pressure Chip Supply Chain
Topco Scientific (TSC) has warned that semiconductor material prices are climbing as higher upstream petrochemical costs ripple through the chip manufacturing supply chain. During its second-quarter 2026 earnings conference, the company said key materials used in semiconductor production, including photoresists and thermal interface adhesives, are seeing price increases of up to 15%.
The rise in costs highlights a growing challenge for the semiconductor industry. Many advanced chipmaking materials rely on petrochemical-based inputs, meaning fluctuations in crude oil, chemical feedstocks, and related production expenses can quickly affect pricing across the supply chain.
Photoresists are essential in the lithography process, where circuit patterns are transferred onto silicon wafers. As chip designs become more advanced, demand for high-performance photoresists continues to grow. Any increase in photoresist pricing can therefore add pressure to semiconductor manufacturers already dealing with tight margins and rising production complexity.
Thermal interface adhesives are also becoming more important as chips generate more heat and require better thermal management. These materials help improve heat transfer between components, supporting performance and reliability in devices such as smartphones, servers, AI accelerators, electric vehicles, and high-performance computing systems.
TSC’s comments suggest that material suppliers and chipmakers may face continued cost pressure if petrochemical prices remain elevated. For semiconductor manufacturers, even moderate increases in material costs can have a broad impact, especially as fabrication processes become more material-intensive.
The reported price hikes also come at a time when global demand for advanced chips remains strong. Growth in artificial intelligence, automotive electronics, data centers, and consumer devices continues to drive investment in semiconductor production. However, rising input costs could influence procurement strategies, supplier negotiations, and overall production planning.
While the semiconductor industry has spent recent years focused on capacity expansion and supply chain resilience, material cost inflation is becoming another factor to watch. If prices for photoresists, adhesives, and other critical materials keep rising, chip producers may need to adjust pricing, improve efficiency, or seek alternative sourcing options.
For now, TSC’s update serves as a reminder that the semiconductor supply chain remains closely tied to broader raw material markets. As petrochemical costs move higher, the impact is being felt in some of the most critical materials used to produce the chips powering today’s digital economy.
