There are a number of benefits to building in the same area as an
existing fab, particularly when it comes to fab support and
infrastructure. Materials support, contractor support, vendor
support, relationships with local authorities, tax breaks, experienced
employee pools, shared internal support systems, and so on. All this
can cut the costs a good bit, improve the margins, and provide a
faster ramp.
Silicon Valley is now dead as a fab center because so many of those
things have petered out and moved to more viable locations. Intel's
flash development/production fab D2 is the last big fab in Silicon
Valley, and it's not very big by today's standards. It's also 200mm -
I don't think there's any 300mm in Silicon Valley, and I doubt there
ever will be. End of an era, and a bit of a shame.
Intel's a good bit more spread out, partly to avoid disabling
disasters, but they're constantly expanding at the existing sites -
Chandler, Rio Rancho, Leixlip, and Aloha/Hillsboro all started out as
smaller fabs (both in capacity and wafer size), and have been expanded
or are expanding to high volume 300mm fabs for the reasons above.
The downsides of too much expansion in one area include the risk of
local disasters disabling the bulk of your production, raising
property values that make it harder to attract workers, and stretching
the resources too thin, but money attracts solutions to everything
except the disaster avoidance.
Their other options are the existing sites in the US, but there are
issues with those. The old Sunnyvale Development Center and the
Austin fabs are Spansion now, I believe (and still 200mm), and their
old San Antonio fab was bought out by Sony, IIRC. Austin's probably
the best bet, but retrofitting old fabs from 200mm to 300mm is an
expensive challenge even if Spansion weren't using them, and I don't
know if they have enough land there (or local government support) to
build a greenfield fab.
