I am not aware of any SiC or GaN 300mm wafer supply... In fact, I don't even think you can get 200mm substrates with those materials. I think you can grow SiC epi on a silicon substrate, but I doubt that is an efficient way to make power devices. I'm no expert in power, though.

Yes this refers to silicon wafers. Although I am sure Infineon is working on silicon-carbide and gallium-nitride as well.

Without it being mentioned, I guess these devices are still silicon, not SiC or GaN? Wafer thinning and warping is harder for lithography no doubt!

I do not see this rush to lower feature size. Does it truly matter?

If resistance is indeed lower and heat is dissipated more efficiently with same current capacity, it means the efficiency is higher. It sounds a great improvement to me. Any further information and insight?

does the thin wafers will have same current capacity?
