A power outage at one of TSMC's suppliers in Arizona interrupted production at the firm’s Fab 21 in late September, prompting the company to scrap some of the wafers that were in production at the time, according to reliable insider Tim Culpan. A TSMC representative confirmed to Tom’s Hardware that a power outage at a TSMC supplier occurred, but did not confirm if any losses occurred.
The disruption of power supply originated at Linde, a British industrial-gas specialist contracted to support Fab 21. While the power cut did not blackout the fab itself (like other semiconductor production facilities, this one has its own generators to support its operation in case of blackouts), it did cut off delivery of various materials essential for its operation. According to Culpan, TSMC had to stop production for several hours, incurring losses as a result. However, the company has not disclosed how many wafers had to be scrapped (if any), or the financial impact of the outage.
