With supply so limited, prices have nearly doubled in the last year
Why it matters: Exports of crucial semiconductor materials germanium and gallium have been caught up in a game of cat and mouse between the US and China, with Beijing's primary motivation to show that it is able to retaliate against US-led pressures on Chinese companies. China has not been shy about imposing these controls, announcing export restrictions this month on antimony, a mineral used in armor-piercing ammunition, night-vision goggles, and precision optics. Last year, China also introduced controls on exports of graphite and technologies used in rare earth extraction and separation.
Forward-looking: In its effort to become a global tech company, TSMC has long planned to open new plants outside of its Taiwan base. The chip foundry has now confirmed that it will soon begin constructing its first European fab, with support and funding from third-party manufacturers.
