The Three-Tier Structure of Taiwan's Semiconductor Industry
Taiwan's semiconductor ecosystem operates through a well-defined three-tier structure, with each segment playing a crucial and interdependent role in bringing semiconductor products to market. This highly specialized division of labor has allowed Taiwan to develop unparalleled expertise and efficiency across the entire supply chain.
The semiconductor industry in Taiwan can be divided into three major segments: upstream (IC design, materials, and equipment), midstream (wafer manufacturing), and downstream (packaging and testing). Each segment requires specialized technical knowledge, infrastructure, and talent, creating diverse career opportunities throughout the industry.
Upstream: The Foundation of Innovation
The upstream sector represents the beginning of the semiconductor journey, encompassing IC design companies, material suppliers, equipment manufacturers, and IP design firms. This sector focuses on innovation, establishing the blueprints and providing the essential raw materials needed for chip production.
Material Suppliers provide critical components including:
- Silicon wafers
- Specialty gases (such as those from Yadong Industrial Gases)
- Photoresists and chemicals (like those produced by Changxing Materials)
- Target and sputtering materials
Equipment Suppliers deliver the sophisticated machinery essential for chip production:
- Lithography equipment (dominated by Dutch company ASML)
- Etching equipment (from U.S.-based Applied Materials)
- Wafer inspection systems (from American company KLA)
- Wafer cleaning equipment (from Japan's Tokyo Electron)
