TSMC's Earthquake Preparedness: A Case Study in Semiconductor Safety

What safety measures did TSMC implement after the 1999 earthquake?

TSMC implemented seismic isolation systems for tall furnaces and stockers, as well as a flexible pipe system for gas and electricity connections.

How do earthquake sensor networks help in early detection?

Taiwan's earthquake sensor networks provide early warnings to semiconductor fabs, allowing for quick response and evacuation.

What is the financial impact of power outages during earthquakes?

Power outages can lead to significant revenue losses in semiconductor fabs due to work-in-process wafers being discarded.

How did the 2024 earthquake differ from the 1999 earthquake in Taiwan?

The 2024 earthquake had minimal financial impact on fabs due to improved safety measures, unlike the significant casualties and damage caused by the 1999 earthquake.

What technologies are used to protect wafers during seismic events?

FOUPs and Stockers are used in semiconductor fabs to safeguard wafers during processes.

Why are power interruptions a major concern for semiconductor fabs during earthquakes?

Power interruptions can result in lost revenues from infrastructure cuts and business interruptions, impacting the overall financial stability of the fabs.

How do seismic safety technologies reduce stress on equipment during earthquakes?

Seismic isolation systems and flexible pipe systems help minimize damage and ensure equipment integrity during seismic events.

What regions in Taiwan experienced varying levels of ground acceleration during earthquakes?

Hsinchu and Tainan were noted to have different levels of ground acceleration during seismic events.

What emergency measures are in place to mitigate the impact of earthquakes on semiconductor fabs?

Emergency measures are in place to address power outages, but they may not be sufficient for prolonged disruptions, leading to potential losses.

How are lost revenues calculated in semiconductor fabs during earthquakes?

Most reported damages in the billions are attributed to lost revenues from infrastructure cuts and business interruptions, rather than physical equipment damage.
