Imec present roadmap down to 20 Ångström logic devices

From now on I think that it is time to start using Ångström instead of Nanometer (nm) when talking about leading edge CMOS and Memory.  At SEMI:s ISS 2018 (Industry Strategy Symposium) last week Luc van den Hove, Chief Executive Officer and President of Interuniversity MicroElectronics Center (IMEC) presented their roadmap for what future Logic nodes might look like going down to 2 nm that is 20 Ångström.

Key interconnect technologies named "scaling boosters" to reach down to 2 nm may be :
  • Continued scaling of self-aligned contacts
  • Cobalt "Super Via" 20 nm wide
  • Burried Ruthenium Rails only 10 nm wide, which seems to be a evolution of the tungsten burried Word Lines and Bitlines introduced by Qimonda for DRAM (65nm in 2009) except offcourse these rails are burried in a dielectric which will  make it stackable.

Besides the interconnect technologies the presentation showed evolution from FinFETs to nanowire FETs and Imecs latest technology development in 300 mm wafer processing technology:
  • Introduction of triple pattering (Much More ALD!)
  • EUV Litography and the introduction Carbon Nano Tube CNT Pellicle for EUV mask protection
  • Smoothening technology in patterning like Atomic Layer Etching for improving the local critical dimension uniformity (LCDU) down from 2.7 to 1.4 nm
In the case of memory technology Imec now focuses on 4 non-volatile types of memory cells besides DRAM and 3DNAND Flash:
  • STTRAM - spin transfer torque magnetoresistive random-access memory
  • RRAM - resistive random-access memory
  • FeRAM - ferroelectric random-access memory (should be renamed DD-RAM for Dresden)
  • SOTRAM - Spin Orbit Torque random-access memory

  1. To rank a website in 2006 you just needed links back to your website and so buying links / link exchange was all the rage and most websites had a web page where they would list companies and links to their website (I am still amazed how many websites continue this practice).

  4. Then again, too much text is boring. So mix and match the graphics and text on your page, having enough white space so that the page is not plain annoying. Webdesigner Limburg
