How chipmaker TSMC bolstered its foundry to fend of Taiwan’s greatest earthquake in 25 years

Taiwan Semiconductor Manufacturing Firm (TSMC), the semiconductor chip-making juggernaut, evacuated its staff after a 7.4 magnitude earthquake rocked the nation on Wednesday, reporting no main damages. Its workers returned to work solely hours after aftershocks rippled by means of the island. It’s not the corporate’s first rodeo in navigating pure disasters.

TSMC, the first chip provider for Apple and AI darling Nvidia, told Fortune it moved its staff from a few of its manufacturing facilities as a precautionary measure and quickly halted operations throughout the earthquake and its fast aftershocks. Whereas the corporate reported harm in a “small number” of instruments and has an ongoing inspection to evaluate full damages, it mentioned its fabrication crops recovered 70% of instruments inside 10 hours of the earthquake, and that its “critical tools,” similar to its multimillion-dollar excessive ultraviolet lithography instruments, stay unhurt.

“TSMC is deploying all available resources for full recovery, and impacted facilities are expected to resume production throughout the night,” TSMC mentioned in an announcement to Fortune.

The producer, as indicated by their harm limitations, isn’t any stranger to being nimble within the face of pure catastrophe. Taiwan has about 2,200 earthquakes a 12 months, in response to the Central Weather Administration Seismological Center, over 200 of which will be felt. The ubiquity of those occasions has merely pressured the corporate to make obligatory adjustments to its operations.

“Seismic activity is a huge challenge for firms carrying out the most precise manufacturing processes of any industry,” Mark Williams, chief Asia economist of Capital Economics, wrote in an April 3 be aware. “But it is one that Taiwanese chipmakers have grown up with.”

TSMC didn’t inform Fortune the conclusions of its inspection or how the work stoppage will affect enterprise, however there’s a precedent for Wednesday’s setbacks: In 2016, a 6.6 magnitude earthquake shook TSMC’s Tainan fabrication crops. Following the catastrophe, the corporate insisted that the quake wouldn’t affect first-quarter shipments greater than 1%. Certainly, wafer chip shipments noticed a 1.8% quarter-over-quarter dip, however income for the quarter plummeted 8.3%.

“Although the February 6 earthquake caused some delay in wafer shipments in the first quarter, we saw business upside resulting from demand increases in mid- and low-end smartphone segments and customer inventory restocking,” Lora Ho, TSMC senior vice chairman of human assets and then-CFO, mentioned in its 2016 first-quarter earnings report.

Following the catastrophe, TSMC strengthened the ceilings of its amenities with bracings and added stoppers to its tower stocker cabinets to forestall slippage.

Studying from the previous

It took an enormous pure catastrophe for TSMC to start to noticeably revise its protocols and infrastructure. The benchmark for Wednesday’s 7.4 magnitude quake was 1999’s 7.6 magnitude shock, which noticed 2,415 folks killed and over 11,000 injured and precipitated $300 million in damages.

Following the 1999 quake, TSMC improved seismic coefficient, or hundreds offsetting seismic exercise—25% greater than legally required for its new most important buildings—and added extra anchors on its gear. It made extra incremental changes to its infrastructure, together with dampers that disperse kinetic power brought on by earthquakes, that lowered the seismic exercise felt by buildings by 15-20%. In 2015, TSMC put in an Earthquake Early Warning System. The corporate didn’t reply to Fortune’s request for touch upon adjustments it plans to make following Wednesday’s pure catastrophe.

TSMC’s earthquake preparedness is a cross-section of the adjustments Taiwan has made to its infrastructure to mitigate earthquake-related damages and fatalities. Whereas over 300,000 households misplaced energy after the Wednesday quake, 70% of them had energy restored by 9:30 a.m.

Wu Yih-min, a professor of geosciences at Nationwide Taiwan College and a workforce chief on the Nationwide Science and Expertise Heart for Catastrophe Discount, told Bloomberg that Taiwan has developed a catastrophe response workforce prior to now three to 5 years to handle catastrophes. The workforce can scan data on-line to tell the place it sends help and may detect cell alerts and consider screenshots from surveillance footage to evaluate damages and foot site visitors patterns.

“Taiwan continues to develop these technologies, and we have advantages,” Wu mentioned.
