    I thought Wolfspeed was already at 300mm at the start of this year?

      I don't think they're claiming to be first in producing the substrate, just first to process it into functional power devices.

    The summary at the top of that page is:

    Infineon marks innovation milestone with world’s first 300-millimeter power silicon carbide (SiC) wafer

    PBusiness & Financial Press Nov 09, 2026

    Infineon presents industry-first functional power devices processed on 300-millimeter silicon carbide wafers

    Technological breakthrough underlines Infineon’s innovation strength and leadership in power semiconductors and wide-bandgap technologies

    300-millimeter SiC process feasibility lays the foundation for secure, future-proof SiC supply to customers in automotive, renewable energy, industrial and AI data center applications

    Infineon will present the first processed 300-millimeter SiC wafer to the public at the electronica trade show starting 10 November 2026 in Munich

    Can you guys restart DRAM production in Europe again? If 20 or so years ago it was possible, today is the best economical opportunity.

      Memory packaging is non-trivial and Europe currently doesn't have players in that space.

      The primary players are South Korea, Taiwan, the US, and China and most of their capex in the space is in Asia and the US.

        as far as I recall it, packaging wasn't done in Europe even then

    Huh, how does this compare to GaN? Better or worse?

    This may not appear sexy but this is a huge deal. Power semiconductors are critical for most NatSec and industrial usecases.

    You can likely live without a new gaming rig. You likely cannot live without replaceable parts for trucks and cars.

      That's a funny way to frame things. Do you think Infineon is forced to choose between those two markets?
