There is no 32nm node at Intel

In the end, there was no magic, Intel did the obvious and made the transistors different lengths. There are two things to note in the table above, gate pitch and gate length. Compare and contrast that to the Vt and it becomes pretty clear that length is the overriding factor for Vt control in Intel 22nm transistors. Pitch also varies quite a bit, but you need to make structures thicker if you run more energy through them, and pitch is where it plays out. Pitch is now equal 3 times the gate length.  What use of gate scaling ?

99% BAD HARDWARE WEEK: Each design is optimized. In the end, gate pitch decide on overall device performance.
