Maybe indirectly. I was surprised to learn (just Googled it!) that Google TPU chips are mostly designed by Broadcom, who (being mostly fabless themselves) do in turn use a variety of companies such TSMC, Global Foundaries, etc to make them. Not sure if TPUs use latest cutting edge nodes - if so then presumably it is specifically TSMC.
