dylan — AI's silicon interposers are pulling in the older fabs that make power and analog chips

One chain from three items: GlobalFoundries' five-year, $2 billion deal to make silicon interposers for TSMC in New York (volume from the first half of 2028; REX Shares' October 12 chipmaking update carries the same $2 billion figure), the Vanguard–NXP Singapore fab cutting its planned output by a fifth to make room for them, and reported 10–30% price hikes at Taiwan's packaging and test houses. The argument is that AI packaging now bids for the same mature-node capacity as power and analog chips, which is how older fabs get pricing power.

three receipts lately about the dullest piece of silicon in an ai chip: the silicon interposer 1. $GFS signed a 5 year, $2B deal to make it for TSMC in upstate new york. First us source, volume ramp in the first half of 2028. 2. Vanguard and nxp's new singapore fab, built for
