Intel 10nm node to leapfrog the industry once again with QWFET transistors?

Semiconductor expert David Kanter is making bold predictions about the process technology Intel will use for its next two generations. If Kanter is correct, it looks like Intel may once again leapfrog the industry by using a new Quantum Well FET (QWFET) transistor design that incorporates two new materials: indium gallium arsenide (InGaAs) for n-type transistors and strained germanium for p-type devices.

Kanter says he's 80-90 percent confident that Intel will gain the capability as early as 2016 to make 10nm QWFET transistors that achieve excellent transistor performance at nominal operating voltage of around 0.5V. On the other hand, the rest of the industry will be using FinFETs with a nominal operating voltage of around 0.7V and won't be able to catch up with Intel until the introduction of their 7nm node, at least two years later.
At this point, I’d like to share a series of predictions concerning Intel’s 10nm node. I first made these predictions in private with a few friends and colleagues back in 2012, but now is the time to make them rather public.

  • The industry will adopt Quantum Well FETs (QWFETs) that use a fin geometry and high-mobility channel materials to achieve excellent transistor performance at nominal operating voltages around 0.5V (compared to roughly 0.7V for FinFETs)
  • The industry will adopt III-V compound semiconductors (most likely In0.53Ga0.47As, alternatively InSb) for the n-type QWFET channel
  • The industry will adopt strained Germanium (most likely) or III-V materials (as an alternative) for the p-type QWFET channel
  • Intel will adopt QWFETs at the 10nm node (most likely), which will probably go into production in late 2015 or early 2016 (alternatively at 7nm in 2017 or 2018)
  • Intel will probably co-integrate conventional transistors and QWFETs, it is less likely (but possible) that the company will use separate substrates that are packaged together to optimize cost
  • The rest of the industry (e.g., Samsung, TSMC, Global Foundries) will wait until the 7nm node to use QWFETs
  • In his article, Kanter explains Intel’s Components Research Lab has been working on QWFETs for little under a decade and that it looks like the technology is mature enough for an introduction on the 10nm node.
