Over at SemiWiki this guy has this 22 ULP announcements as his number one highlight from the TSMC Symposium. Also, he said that TSMC inserted a comparison slide to 22 FD-SOI. He said the Ion and Ioff currents are right on top of each other.

If the new TSMC 22 ULP is close to 22 FD-SOI in power it will win. SOI wafers are more expensive than normal wafers. They require a bunch of extra processing steps to make them.

The 7nm already uses 4P4E so it's already in manufacturing right? It is smaller relative mask count increase from 3P3E.

It looks like resist has been an issue for getting down to 30 nm pitch.

Yes ULP is ultra low power

In three hours of presentations I only saw one slide comparing TSMC 22 to GF 22 and it went by too quickly for me to get any detail. Unfortunately TSMC forbids taking pictures.

Right, I understand this is a foundry output number for all foundries. You have to agree this is pathetic volume at 10K wafers per month.

What I would like to know is what is the PPA comparison between TSMC 22 ULP and FD-SOI 22. Did they say this will be similar? If so, FD-SOI 22 is toast.

I assume ULP means ultra low power process?

Gartner means processed wafers from a foundry or IDM, not raw wafers

Hmmm, interesting. I can't explain it.

Intel should buy them.

@Violoncelles Read the article again.

 

The news comes the same day NXP announced it will use FD-SOI for multiple future processors. So far, a total of just 10,000 FD-SOI wafers/month are shipping from all fabs including Globalfoundries and STMicroelectronics, said Sam Wang, a chip analyst for Gartner.

I take this to mean all FD-SOI wafers worldwide coming out of Soitec including the GloFo 22.

Intel is another one with no FD-SOI.

FD-SOI transistor is an interesting device with the back-bias, but the fourth terminal makes it a larger cell at a given design rule.
