Is there a wafer producing company that could produce 16" GaN wafers?

[wants_to_know]

Hi,

I am currently investigating whether there exists a company that could produce GaN wafers (ideally 16"), carboncompensated. So far, I didn't have much luck and only found companies that could produce small ones. Do any of you have an idea who might be able to produce 16" GaN wafers?

the biggest fabs are 12''... next generation coulbe be 18'' but it's been delayed.
GaN is a niche business, no reason to invest into a 12'' fab for this techno. probably the best you can find is 8''...

I believe GaN wafers are only available up to 75mm for a GaN wafer. GaN on SiC or Si is available up to 150mm but it is only a film on top of a wafer made of another material.

Yes, this is the problem we ran into. We'd need big wafers and not just wafers with a thin layer on top.

Also, who might be able to produce such wafers at all?

Thanks for all the replies so far nevertheless!

I suggest contacting Jeehwan Kim at MIT

I suggest contacting Jeehwan Kim at MIT where he is perfecting a process to produce 8 inch GaN using a lift off process from a Graphene base ensuring control of the GaN crystallography.
