The semiconductor value chain consists of several key categories: Design (IP), Electronic Design Automation (EDA), Fabless Design, Foundries & OSAT, Integrated Device Manufacturers (IDM), Chemical & Wafer suppliers, Equipment manufacturers, and finally, the companies that integrate semiconductors into electronic products.

Understanding how these different segments interact is crucial to appreciating the complexity and innovation behind the devices we use every day.

Design (IP) – The Foundation of Innovation

At the core of semiconductor development is Intellectual Property (IP) design. Semiconductor design companies create the blueprints for chips that define their functionality and performance. These designs include complex layouts of transistors and logic circuits optimized for power efficiency, processing speed, and specialized applications such as AI, 5G, or IoT. Some of the most critical semiconductor IPs are developed by companies such as ARM, Imagination, which license their technology to chipmakers worldwide. Emerging players are also making an impact by focusing on open-source architectures and energy-efficient designs. The growing complexity of chip design is leading to a rise in demand for IP customization, where companies are tailoring solutions to meet specific application needs, such as high-performance computing or low-power IoT devices.

Electronic Design Automation (EDA) – The Tools That Enable Complexity

Given the extreme complexity of modern semiconductor designs, engineers rely on specialized software tools known as Electronic Design Automation (EDA) to create, simulate, and verify chip designs before manufacturing. EDA tools help engineers model circuits, optimize performance, and ensure that a design can be manufactured efficiently in a factory. Industry leaders such as Synopsys, Cadence, and Siemens EDA provide these essential tools, enabling the entire semiconductor ecosystem to function at the cutting edge. Continuous innovation in AI-driven chip design is also transforming the way semiconductors are developed, reducing time to market and improving efficiency. The growing adoption of cloud-based EDA tools is further revolutionizing the industry, allowing global teams to collaborate seamlessly on chip development.

Fabless Design – The Architects of Semiconductor Innovation

Many of the world's most well-known semiconductor companies, including NVIDIA, Qualcomm, and AMD, follow a fabless business model, meaning they design and market chips but do not own manufacturing facilities. Instead, they focus on developing high-performance processors, graphics units, and specialized chips, outsourcing the actual fabrication to foundries. This model allows them to concentrate on innovation without the high capital investment required for semiconductor manufacturing. The rise of AI and machine learning applications has led to a growing demand for customized chips, further driving innovation in the fabless sector. Additionally, startups focusing on application-specific integrated circuits (ASICs) and domain-specific architectures are gaining traction, offering optimized solutions for AI, 5G, and automotive industries. Some major manufacturers of electronic products now have teams designing their own chips as well to ensure their requirements are properly met.

Foundries & OSAT – The Makers of Silicon

Foundries are the front-end facilities that manufacture semiconductor chips based on the designs provided by fabless companies or outsourced by IDMs. Leading foundries such as TSMC, Samsung Foundry, United Microelectronics Corporation, and GlobalFoundries use advanced lithography techniques to produce cutting-edge semiconductors. Because chip fabrication is a highly sophisticated and capital-intensive process, foundries operate at an enormous scale, producing millions of chips with nanometer precision.

Once chips are manufactured, they must be tested and packaged before they can be integrated into final products. Outsourced Semiconductor Assembly and Test (OSAT) companies (back-end process), such as ASE, Amkor, and JCET, handle these processes, ensuring that each chip meets rigorous quality standards before it is shipped to electronic manufacturers. As demand increases for advanced packaging techniques, OSAT companies are playing an even more critical role in enhancing semiconductor performance. The rise of 3D packaging and chiplet-based architectures is pushing OSAT firms to develop innovative assembly methods that improve efficiency and performance.

Integrated Device Manufacturers (IDM) – Combining Design and Production

Unlike fabless companies, Integrated Device Manufacturers (IDMs) own both the design and manufacturing operations, giving them end-to-end control over semiconductor production. Companies such as Intel, Samsung, and Texas Instruments follow the IDM model, which allows them to tailor their manufacturing processes to optimize performance for their specific chip designs. This vertical integration enables them to innovate rapidly and maintain high levels of quality and security throughout production. IDMs are also investing in expanding their fabrication capacity to reduce reliance on external foundries and ensure a more resilient supply chain. Recent trends show IDMs increasingly collaborating with third-party foundries for specific process nodes, balancing flexibility with in-house production.

Chemical & Wafer Suppliers – The Raw Materials of Semiconductors

Semiconductor manufacturing requires highly specialized raw materials, particularly silicon wafers and various chemicals used in photolithography, etching, and deposition processes. Companies like Shin-Etsu Chemical, Sumco, and GlobalWafers produce ultra-pure silicon wafers, while others supply high-performance gases, resists, and solvents essential for chip fabrication. The precision and purity of these materials are critical for ensuring that semiconductor manufacturing processes meet the highest standards of performance and reliability. As sustainability concerns grow, many suppliers are investing in greener and more efficient production methods, including recycling chemicals and reducing water usage in wafer production.

Equipment Manufacturers – The Enablers of Advanced Fabrication

Building semiconductor chips requires some of the most advanced equipment in the world. Companies such as ASML, Applied Materials, and Lam Research provide the lithography machines, etching systems, and deposition tools that make high-performance chip manufacturing possible. ASML’s extreme ultraviolet (EUV) lithography machines, for example, are essential for producing the most advanced chips at 3nm and beyond. Innovations in semiconductor equipment help extend Moore’s Law, producing faster, more efficient chips with each new generation. Investment in new fabrication technologies, such as high-NA EUV and quantum computing materials, is expected to drive the next wave of semiconductor advancements.

Manufacturers of Electronic Products – Bringing Chips to Consumers

Finally, semiconductor chips are integrated into electronic devices by manufacturers such as Tesla, Bosch, Siemens, Haier, and Schneider Electric. These companies design products that leverage semiconductor technology to create electric vehicles, industrial automation systems, medical devices, and more. The growing demand for AI, IoT, and autonomous systems is further driving the need for specialized semiconductor solutions, particularly in edge computing and real-time processing applications.

Global Cooperation – A Necessity for the Semiconductor Industry

The semiconductor value chain is a prime example of global interdependence. No single country or company can master every aspect of chip design, manufacturing, and equipment production. Instead, different regions have developed specialized expertise, while emerging players, backed by substantial government funding, are making strides to close the technology gap and establish themselves in the industry. The value chain is also evolving, with significant shifts on the horizon. ARM is set to debut its first in-house chip by summer, signaling a move beyond its traditional role as an IP provider and into chip design. Meanwhile, Intel's future remains uncertain following the departure of CEO Pat Gelsinger in December 2024, raising questions about the company’s long-term strategy as an IDM and competitiveness. At the same time, startups are making significant investments in specialized areas of the value chain, introducing innovations that could disrupt the industry's traditional dynamics.

To ensure a stable and resilient supply chain, international cooperation and strategic partnerships are essential. The industry’s complexity and capital intensity make it impossible for any nation or company to go at it alone. Attempts at full vertical integration remain unrealistic in the near term, reinforcing the need for alignment across borders. Challenges such as geopolitical tensions, supply chain disruptions, and sustainability concerns will continue to shape the industry's future. Without global collaboration, the semiconductor industry's progress, economic stability, and technological leadership could be at risk. Only through strengthened international partnerships can the sector ensure long-term resilience, innovation, and sustainability.
