So we're really excited right now because our – frankly, our 10 nanometer yields are ahead of where we thought they would be. So we're extremely bullish on the node at this point and it's really just having us trying to finish out two CPUs in a calendar year.
Unidentified Analyst
That’s good news on 10 nanometer. And any confidence that second half 2020, we feel pretty good, line in the sand that it's coming out?
Jason Grebe
Yes. We feel really good about our second half guide there.
Unidentified Analyst
Sure. And then a lot has been talked about the issues with 10 nanometer. Why do you think the yields are ahead of plan? Is it just we finally figured it out? Or…
Jason Grebe
Yes. So the quick history on 10 nanometer was typically when we go for a scaling benefit on node to node, it's been a 1.5 to 2x type range. When we went from 22 to 14, we were – we did 2.42x scaling, which was very aggressive when we pulled it off. On the next generation from 14 to 10, we went for even more scaling from 14 to 10, and in order to do that, we had to do a bunch of quad patterning, a very complicated silicon development. That caused a lot of delays and a lot of the yield issues. We've overcome all those.
The yield curves that we've been watching every week coming out of the factory, both in our development factories and our HPM factories are right on track and actually slightly ahead. So that we've kind of gotten over the learnings that we have to get over and we're ramping the process now.
Unidentified Analyst
Did EUV or lack of EUV at 10 nanometer had anything to do with the issues?
Jason Grebe
Yes, I would say the delays in EUV had us move down a multi-patterning path, which caused some of the delays for sure and now we're moving to EUV when we get to 7 nanometer.
Unidentified Analyst
Yes. That was my next question. So how do we feel about EUV 7 nanometer, in the bag, stone cold pipe lock?
Jason Grebe
Yes. It's done. It’s basically done. No. I feel really good about 7 nanometer. We are on a path right now to have a two-year cadence from 10 to 7. Everything from a development perspective on a power and a performance and a timing cadence perspective on 7 nanometer look really good. So we're really bullish on a 2021 product launch on 7 nanometer.
Unidentified Analyst
By the way, we do have some time left and I'd like to open it up to the audience if anybody has any questions or else I'll keep going. Anybody out there? Going once, going twice. Just to dig in a little more on EUV, what were the issues with the – at 10 nanometer to the extent you can…
Jason Grebe
I think we just weren't ready from a learning curve perspective to put it in the process development or a timing perspective and we were going to delay till 7.
