The 3-Nanometer Chip Crisis: How China Fights Back with Rare Earths and Quantum Technology Amid Japan's Supply Cut of Photoresists

A silent technological war On April 3, 2025, a ban from the Japanese government shook the global semiconductor industry—export controls on EUV (Extreme Ultraviolet) photoresists to China. This seemingly ordinary chemical material actually chokes the throat of China’s 3-nanometer chip manufacturing. As I pored over the financial reports of Japan’s JSR Corporation late at night, … Read more
