Semiconductors, often called the "rice of industry," have become pivotal to both the digital economy and global security, evolving from trade commodities to central elements in national security strategies. Amidst this shift, major global powers, notably the U.S. and China, are competing for dominance in the semiconductor sector, fueling a 'semiconductor war' to reorganize supply chains and bolster domestic high-tech industries. This global competition has compelled leading nations such as Korea and Taiwan to escalate their support for their respective semiconductor industries.
