TSMC stated that to ensure personnel safety, part of the plant area has been evacuated according to internal procedures, and the safety system is normal; detailed information is still pending confirmation. Some quartz tubes in TSMC's plant have ruptured, causing some damage to online wafers. Some machines have been temporarily shut down for inspection to prevent deviations. Based on the current situation, it is estimated that the impact on working hours will be within 6 hours, with an estimated impact of about $60 million on TSMC's second-quarter financial forecast, with overall limited impact.
