The Intel Nanometre
As the world now knows, there’s a nanometre and then there’s an Intel nanometre.
To most of us a nanometre is a nanometre but, to Intel, a nanometre measures 1.182 nanometres.
We know this because the measure of a semiconductor manufacturing process is the drawn gate length.
And, on Intel’s so-called 22nm process, the drawn gate length is 26nm.
Which means an Intel nanometre measures 1.182 nanometres in rest-of -world measurement terms.
That means Intel’s 14nm process, for which it is currently building fabs is, presumably, what the rest of the world would call a 16.55 nanometre process.
Which puts Intel’s 14nm process pretty much on a par with the foundry industry’s 20 nanometre process, and behind TSMC’s 16 nanometre finfet process and Globalfoundries’ 14nm process.
Unless, of course, the ‘Intel nanometre’ has been re-defined and the Intel nanometre now has a new value – maybe the Intel nanometre now measures 1.25 nanometres? Or even 1.5 nanometres?
