Core Viewpoint - The article emphasizes the critical need for a resilient and self-sufficient semiconductor supply chain in the U.S., highlighting the significant investments required to address material shortages and support semiconductor manufacturing growth [1][2][3]. Group 1: Investment and Supply Chain Challenges - The U.S. plans to invest over $450 billion in semiconductor manufacturing capacity by 2024, but faces a potential shortfall in the supply of over 60% of the necessary materials and chemicals by 2030 [1][10]. - An estimated one-time capital investment of around $9 billion is needed to fill the material gap and keep pace with semiconductor manufacturing capacity expansion [2][13]. - The overall semiconductor market in the U.S. is projected to exceed $140 billion by 2030, more than doubling from $68 billion in 2024, with related chemicals and materials demand expected to grow from $4 billion to approximately $13 billion [3]. Group 2: Importance of Chemical Supply - The semiconductor industry relies on over 100 types of chemicals and materials, many of which require ultra-high purity, making the supply chain vulnerable to disruptions [8][10]. - The U.S. currently imports nearly all ultra-high purity hydrogen fluoride needed for advanced semiconductor devices, indicating a heavy reliance on foreign supply chains [8][10]. - A diversified chemical supply chain is essential for supporting U.S. semiconductor manufacturing without significantly impacting overall manufacturing costs, as raw materials account for less than 5% of total costs [8]. Group 3: Types of Chemical Supply Gaps - Seven types of chemical supply challenges have been identified, ranging from attractive domestic supply to critical gaps in technology and raw material access [9][18][21]. - For example, high-purity hydrogen fluoride faces economic challenges due to reliance on imports, while some materials are restricted due to environmental regulations [21][22]. - The article outlines the need for collaboration among industry players to develop local supply chains and reduce dependency on imports [27]. Group 4: Future Directions - To ensure a reliable supply of critical materials, companies should consider trade agreements, securing key raw material sources, and addressing investment and operational cost disparities in the U.S. [27]. - The establishment of resilient semiconductor material supplies is crucial for scaling the domestic semiconductor industry and securing access to key technologies in the 21st century [27].
