The global silicon EPI wafer market was valued at USD 1.6 billion in 2024 and is estimated to grow at a CAGR of 13.2% to reach USD 5.5 billion by 2034 with the volume of 39.4 thousand units. The growth of the market is driven by key factors such as expansion of automotive electronics, increasing adoption of IoT and edge devices, as well as growing investments in semiconductor manufacturing.
The tariffs on imported semiconductors, such as Taiwan, China, and South Korea, during Trump’s administration are a substantial concern for the US Silicon Epitaxial Wafer Market. The trade tariffs (potentially up to 100%) increase the price of vital semi-conductor components, thus upsetting the entire pricing system within a domestic industry's semiconductor value chain. Consequently, American manufacturers lose their global cost competitiveness and significantly increase production expenses. Firms have to resort to relocating fabrication plants—with their huge upfront capital investments and lengthy lead times which will further decimate supply chains. These tariffs also stand to damage international relations and further escalate disputes over the oversupply of semiconductors.
