### Kumamoto Earthquake Warns of Semiconductor Supply Crisis, What Are the Definitive Investment Opportunities for Domestic Substitution? Time: 2026-07-31 10:10:07 Content: Recently, a strong 7.1-magnitude earthquake in Kumamoto, Japan, directly hit the most fragile "single-point concentration" weakness of the global semiconductor supply chain. Kumamoto alone hosts Sony's CIS fab with a 50% global share, Renesas' automotive MCU fab with a 30% share, and Tokyo Electron's coater/developer equipment base with a 90% share. In addition, Mitsubishi Electric's power semiconductors, Ebara's equipment components, and TSMC's JASM mature-process wafer foundry all halted production simultaneously. Under the global AI-driven semiconductor super-cycle, this earthquake is by no means a short-term disturbance, but directly pushes domestic substitution from "concept speculation" to a substantive window for customer verification and order transfer. The entire A-share semiconductor supply chain may usher in a golden investment stage driven by both "high demand growth + supply gap." ...
