I got a package today containing a chip. Some shipping label markings
include:
From: Norwood, Massachusetts, USA (Guess who!)
Country of Assembly: South Korea
Country of Diffusion: Ireland
It turns out “country of diffusion” is where the silicon dies are manufactured. From there they are inexplicably transported to a cleanroom on the opposite side of the globe where they are mounted and wirebonded into their plastic packages. Then to a warehouse in exurban Boston, where they are re-packaged for shipment to (a) real customers and (b) people like me.
Stupid “global economy.”
