Intel claims 7nm is developed by a separate team and largely a separate effort, unrelated to the 10nm struggles:
“7 nm for us is a separate team and largely a separate effort. We are quite pleased with our progress on 7 nm. In fact, very pleased with our progress on 7 nm. I think that we have taken a lot of lessons out of the 10 nm experience as we defined that and defined a different optimization point between transistor density, power and performance and schedule predictability. […] So, we are very, very focused on getting 7 nm out according to our original internal plans.”With 7nm, Intel is moving back to a 2x scaling factor, which suggests a rather extensive use of EUV:
“One thing I will say is that as you look at 7 nm, for us this is really now a point in time where we will get EUV back into the manufacturing matrix, and therefore, I think, that will give us a degree of back to the traditional Moore’s Law cadence that we were really talking about,”Via: AnandTech
“[With 7 nm] we are going back to more like a 2X scaling factor […] and then really moving forward with that goal.”
