Semiconductor Value Chain Explained, from Design to Equipment and Distribution

TL;DR

• The semiconductor value chain splits into design (IP·EDA), manufacturing (wafer·foundry), assembly & test, equipment & materials, and distribution.
• Each stage is highly specialized and geographically concentrated, creating reliance on specific countries and firms and making the chain vulnerable to supply risks.

Overall Flow and Key Roles

Semiconductor products start with design, then move to manufacturing, assembly & test, and final distribution. The design stage is heavily R&D driven, producing circuits and IP, while manufacturing handles wafer processing and process technologies. Assembly and test place chips into packages and verify performance and reliability. Equipment and materials underpin every stage and form the supply chain foundation.

Stage-by-Stage Summary

1. Design

• Function: Development of semiconductor circuits, system-on-chip (SoC), IP blocks, and electronic design automation (EDA) tools.
• Characteristics: High R&D investment and concentrated talent. Designers rely on outsourcing production to foundries.

1. Manufacturing (Foundry·Wafer Fab)

• Function: Wafer processing, lithography, etching, ion implantation and other process steps.
• Characteristics: Massive capital expenditure and dependence on equipment. Advances in process scaling increase demands for equipment and materials technology.

1. Assembly & Test

• Function: Die singulation, bonding, packaging, and electrical and environmental reliability testing.
• Characteristics: Direct impact on final product performance and yield. Advanced packaging technologies are rising.

1. Equipment & Materials

• Function: Supply of lithography, etch, deposition equipment and specialty gases, photoresists and other materials.
• Characteristics: High technology barriers and market concentration among a few suppliers.

1. Distribution & Applications

• Function: Supply to final product manufacturers, ODMs, and customers, plus after-sales service.
• Characteristics: Demand volatility and comprehensive logistics capability are important.

Supply Chain Risks and Geographic Concentration

• Key equipment and advanced processes are often concentrated in specific countries, creating geopolitical risk exposure.
• Raw materials, specialty gases, and high-purity chemicals are difficult to diversify in sourcing.
• Imbalances in supply and demand can propagate across stages, making inventory management and partnerships critical.

Summary Table

The semiconductor industry is highly specialized across stages, with frequent collaboration and outsourcing. Latest specific figures, regulations, or tax rates may change, so please confirm with official sources such as securities firms or the national tax agency.
