How big is Giga?
the illustration above show two site plots with manufacturing and support buildings with approximate external dimensions and in the same scale.
The Fab on the left side was recently opened with buildings for Cleanroom 1. The builder says that this is the largest single investment in the history of their company. The right Fab is in operation with Cleanroom 1 and the buildings for Cleanroom 2 are currently under construction.
- Site plot: 17 times bigger
- Cleanroom: 14 times bigger in full buildout
- Investment: 1.2 bill. US$ (left with cleanroom 1) vs. 24 bill. US$ (right, full expansion)
Some thousand square meter cleanroom are not small. 70,000m² cleanroom is Giga, especial if as ballroom and with full subfab!
Fab sizes according TSMC: Mini ~10k, Mega ~25k and Giga >100k wspm. TSMC Fabs 12, 14 and 15 are Gigafabs, Samsung, YMTC, SK Hynix, SMIC, Nexchip, GF and Intel are also on the Gigapath.
Economy of scale is getting an more and more important key element for successful semiconductor production. The Gigarace is in full swing. Leaders are fast and clearly in front.
It can be assumed that Fabs have to get that big to be competitive, and this for an continuous growing bandwidth of products
So what are the most important success factors in the chip race? Process technology, time to market, yield, less expensive Fabs, deep pockets or all together?
