Interposer

It certainly takes it into high-end packaging, but would leading-edge transistor fabrication follow? Well, not necessarily.

Interposers need sophisticated processing and high-density connections, but they don't require the same kind of advanced fab technology.

Nevertheless, I think this is a significant pull towards the high end.

Right now, you could say GlobalFoundries is capturing parts of the high-end computing without actually moving towards the leading edge of transistor fabrication.
