Silicon and other semiconductor raw materials are melted and cast in the form of a large cylinder called an ingot and then sliced into wafers. Wafers are then used to create the integrated circuits. By comparing the trade balance of wafers with that of raw materials, we can see that the top net importers of raw materials are also the top net exporters of wafers, confirming that countries like Japan and China import raw materials for the production of wafers.
| Country | Share of Raw Material Exports |
|---|---|
| EU | >30% |
| Japan | ~40% |
| US | Significant |
Sustainability in Raw Material Sourcing
Sustainability in raw material sourcing is becoming increasingly important. Efforts are being made to ensure that the extraction and processing of these materials do not harm the environment. This includes reducing carbon footprints, recycling materials, and ensuring ethical labor practices in the supply chain.
Manufacturing and Fabrication Processes
Leading Semiconductor Manufacturers
The semiconductor manufacturing industry is dominated by a few key players who have established themselves as leaders in the field. These companies operate fabrication facilities (fabs) where integrated circuits are printed by layering transistor elements onto raw silicon wafers. The precision required in these fabs is unparalleled, making semiconductor manufacturing one of the most demanding industries worldwide.
Advanced Fabrication Techniques
Advanced fabrication techniques are essential for improving yield and quality of wafers in the semiconductor manufacturing sector. These techniques involve the use of highly specialized and sensitive equipment to ensure the highest degree of precision. The manufacturing process is divided into front-end and back-end processes. The front-end process involves forming circuits on the wafer, primarily handled by specialized companies called foundries. The back-end process includes wafer dicing, packaging, and testing, often conducted by foundries or assembly and testing companies.
Quality Control in Manufacturing
Quality control is a critical aspect of the semiconductor manufacturing process. It ensures that the final products meet the stringent standards required by the industry. Quality control measures are implemented at various stages of the manufacturing process to detect and rectify any defects. This is crucial for maintaining the reliability and performance of semiconductor devices.
Testing and Quality Assurance
Importance of Testing in the Value Chain
Testing is a crucial stage in the semiconductor value chain that ensures the reliability and performance of the final products. These tests and inspections scrutinize semiconductors from the raw wafer to the final product. Identifying and removing any defective products through performance testing helps to ensure the reliability of the semiconductors.
Major Testing Companies
Several companies specialize in the testing and quality assurance of semiconductors. These companies are often referred to as Outsourced Semiconductor Assembly and Test (OSAT) companies. They play a significant role in the back-end segment of manufacturing, particularly in regions outside of Japan. Some of the leading OSAT companies include:

The technologies used in semiconductor quality control are continually evolving. Advanced techniques such as automated optical inspection (AOI), X-ray inspection, and electrical testing are commonly employed. These technologies help in detecting defects at various stages, ensuring that only high-quality semiconductors reach the market.
Packaging and Assembly
Packaging in the semiconductor industry is crucial for protecting chips from physical damage and environmental factors. Advanced packaging techniques provide better heat management during operations, allowing companies to place semiconductor components closer together. This results in higher data-transfer rates and better performance. Additionally, advanced packaging allows semiconductor companies to combine mature and leading-edge chips in an integrated system, which lowers costs.
The semiconductor packaging industry includes several key players who specialize in various aspects of the process. Some of the top companies in this sector are:

The assembly process in semiconductor manufacturing involves cutting, separating, testing, and assembling individual chips for integration into final products. This portion of the supply chain is referred to as Assembly, Test, and Packaging (ATP). While ATP generally involves fewer complex processes and tools than other portions of the semiconductor manufacturing supply chain, it is more labor-intensive. However, with each successive shrinking of transistor size and density, ATP has quickly become more complex. Advanced assembly techniques now allow for better heat management and higher data-transfer rates, making them essential for modern semiconductor applications.
Distribution and Sales Channels
