From the source below, 2017-2019 for 7 nm seems pretty close to my previous comment's 2018 timeline. Again, what were the reasons for pushing 7 nm out to 2024?
"And note that a 2015 450mm pilot line coincides with what is expected to be the 10nm node at leading edge, and 2017-2019 could be 7nm or even 5nm."
If Intel is shipping 22 nm in 2012 and on pace to deliver 14 nm in 2014, at that pace it would be 10 nm in 2016 and 7 nm in 2018. Is there some reason to believe that suddenly the pace is going to fall off dramatically between now and 2018?
It will be interesting to see the impact on design flows. I think digital won't change that much (will graphene use GDS?), but as for analog flow it might be different. Will good old Spice stay in line?
The period with CMOS and graphene (or any other successor) co-existing might be tricky. How about mixed technology, like it was for bipolar and CMOS?
2024 is not very far away from now! If graphene is going to be the next technology in electronics, we need to start more education now. At least engineering students have to learn more about this new material to be well prepare for the next generation electronics!
