The Taiwan Semiconductor Manufacturing Company (TSMC) will adopt safety measures at its facilities as the ongoing pandemic starts to infect more people in Taiwan. TSMC's home territory has seen cases surge over the past few days, and even though the figure remains low compared to other countries, investors did not view this favorably today. This was evidenced by share prices of most companies dropping during trading, with TSMC losing 2.3% of its market value, roughly equal to NT$389 billion.

The fab's responses came alongside other chipmakers and companies such as United Microelectronics Corporation (UMC), who followed lockdown restrictions imposed in some part of the island. Taiwan's capital city Taipei witnessed the toughest pandemic-related measures so far as authorities imposed a Level 3 alert, just one level short of Level 4, which is a complete lockdown.
