Since the global economic recession of 2008-2009, the IC industry has been on a mission to pare down older capacity (i.e., ≤200mm wafers) in order to produce devices more cost-effectively on larger wafers. The spree of merger and acquisition activity and the migration to producing IC devices using sub-20nm process technology has also led suppliers to eliminate inefficient wafer fabs. From 2009-2017, semiconductor manufacturers around the world have closed or repurposed 92 wafer fabs, according to data compiled, updated, and now available in IC Insights’ Global Wafer Capacity 2018-2022 report.
Figure 1 shows that since 2009, 41% of fab closures have been 150mm fabs and 26% have been 200mm wafer fabs. 300mm wafer fabs have accounted for only 10% of total fab closures since 2009. Qimonda was the first company to close a 300mm wafer fab after it went out of business in early 2009.
