Semiconductor demand and digital transformation are driving growth.

As reliance on digital technology increases, demand for silicon wafers is also surging.

• AI and Data Centers: The rise of generative AI and large-scale language models (LLMs) is driving a sustained increase in demand for 300mm wafers for state-of-the-art logic chips and high-bandwidth memory (HBM).

• Next-generation communications: The proliferation of 5G infrastructure and the increase in IoT devices are accelerating semiconductor production and directly impacting wafer consumption.

• Transition to advanced nodes: With miniaturization processes below 3nm, the demand for higher quality, less defective wafers is increasing, which is driving up market prices (ASP).

The automotive and industrial sectors are driving market expansion.

The automotive industry is emerging as a major growth driver.

• Electric Vehicles (EVs) and ADAS: The proliferation of EVs and the incorporation of advanced driver-assistance systems (ADAS) are increasing the amount of semiconductor content per vehicle, thus increasing the need for high-quality silicon wafers.

• Industrial Automation: The advancement of Industry 4.0 is driving increased demand for sensors, microcontrollers, and power devices.

• Evolution of power semiconductors: While there is a shift towards next-generation materials such as SiC (silicon carbide) and GaN (gallium nitride), conventional silicon substrates still play a central role in power control.

Market Segmentation: 300mm wafers and memory applications lead the market.

Segment analysis:

• By type

• 300mm wafers (the mainstream in state-of-the-art manufacturing due to their efficiency and cost-effectiveness)

• 200mm wafers, small diameter wafers

• By application

• Memory (leading due to data storage demand for cloud and AI applications)

• Logic/MPU, Analog, Discrete Devices & Sensors

• By end user

• Consumer electronics (the largest segment due to continuous innovation)

• Automotive, Industrial & Communications, Computing & Data Storage

Emerging opportunities in advanced materials and government-led initiatives

• 300mm wafers for advanced nodes: Demand for AI processors is tightening supply, leading to long-term supply agreements (LTAs) between major manufacturers and IDMs (vertically integrated manufacturers).

• Development into compound semiconductors: The growth of SiC and GaN wafers is bringing new added value to the traditional silicon market.

• Government support measures: Semiconductor subsidies in various countries (such as the CHIPS Act) and efforts to strengthen domestic production capacity are supporting the stabilization of supply chains and long-term growth.
