Intel to present 3D stacked Nanoribbon Transistors for Continued Moore’s Law Scaling at IEDM 2020

Intel to present stacked gate-all-around FET (GAA-FET) technology, i.e., a complementary FET (CFET) at IEDM2020. In CFETs, the idea is to stack both nFET and pFET wires on each other. A CFET could stack one nFET on top of a pFET wire, or two nFETs on top of two pFET wires. This ‘folding’ of the nFET and pFET eliminates the n-to-p separation bottleneck, reducing the cell active area footprint (LINK). Please find the announcement below:

Home-2020 - IEDM 2020 ieee-iedm.org IEDM Conference 2020. To Be Held Virtually December 12-18. The on demand portion of the conference will begin on December 5th. Intel to present 3D stacked Nanoribbon Transistors for Continued Moore’s Law Scaling: 

Stacked NMOS-on-PMOS Nanoribbons: From planar MOSFETs, to FinFETs, to gate-all-around (GAA) or nanoribbon devices, novel transistor architectures have played a critical role in driving performance predicted by Moore’s Law. Intel researchers will describe what may be the next step in that evolution: NMOS-on-PMOS transistors built from multiple self-aligned stacked nanoribbons. This architecture employs a vertically stacked dual source/drain epitaxial process and a dual metal gate fabrication process, enabling different conductive types of nanoribbons to be built so that threshold voltage adjustments can be made for both top and bottom nanoribbons. The approach combines excellent electrostatics (subthreshold slope of <75 mV/dec) and DIBL (<30mV/V for gates ≥30nm) with a path to significant cell size reduction due to the self-aligned stacking. These devices were used to build a functional CMOS inverter with well-balanced voltage transfer characteristics.

    1. I really want to thank Dr Emu for saving my marriage. My wife really treated me badly and left home for almost 3 month this got me sick and confused. Then I told my friend about how my wife has changed towards me. Then she told me to contact Dr Emu that he will help me bring back my wife and change her back to a good woman. I never believed in all this but I gave it a try. Dr Emu casted a spell of return of love on her, and my wife came back home for forgiveness and today we are happy again. If you are going through any relationship stress or you want back your Ex or Divorce husband you can contact his whatsapp +2347012841542 or email emutemple@gmail.com website: Https://emutemple.wordpress.com/ Https://web.facebook.com/Emu-Temple-104891335203341

  4. I got Diagnosed with Herpes, I have be dealing with Herpes for the past 4 years. On till I got review online about natural cure people testifies how DR. Ehimare cure them with his herbal treatment. And I order the treatment, after taking it for 21 days I totally got cured with DR. Ehimare treatment. I'm recommending you diagnosis with herpes should get this treatment and be cured of it you can contact his email address via; drehimare3@gmail. com or you can also call or whatsapp +1 (267) 691-1087Dr. Ehimare also cure the following virus and many more... 1} Cancer 2} Diabetes 3} Hepatitis 4} fibroid 5} herpes 6} Lupus

  5. I contacted herpes' I was told there is no herpes cure except treatment to
    control it. I totally lost hope. All I could think was losing my life it
    was so embarrassing to have this virus, few weeks ago I ready about a
    possible natural herbs cure which was guaranteed. And I ordered the natural
    herbs treatment from Dr voodoo after some weeks I got 100? cure. Now I'm so
    excited to share this testimony contact Dr voodoo WhatsApp number
    +2348140120719 also e-mail him at: voodoospelltemple66@gmail.com

  6. Hello viewers I am glad to have met with the powerful herbal healer called
    Dr voodoo who use his herbs to cure my HIV disease I suffered from 15years,
    but now I am a happy woman and i am free from this sickness that has been
    problem to my living, after using Dr voodoo herbal medicine within 1week i
    was diagnose negative, I will recommend Dr voodoo to everyone reading this
    article because this herbal healer is capable to heal anything, the
    scientist said has no cure, Email him : voodoospelltemple66@gmail.com or
    add Dr voodoo on whatsApp: +2348140120719

  7. Oral herpes is a bothering virus, but overcoming is possible,I was diagnosed with genital herpes type 1 (hsv1),i contacted Dr voodoo his Email voodoospelltemple66@gmail.com for treatment where i heard and read about Dr. voodoo on a forum. After Three weeks of herbal medication i went for test and i was tested negative from Herpes thank you Doctor,Here is Dr voodoo WhatsApp's number +2348140120719

  8. Hello everyone. DARK WEB CYBER HACKERS are the best. They changed my life back in 2021 when i had no money to take care of things, i met them online while browsing on the internet one night , i went to there website ( www.darkwebonlinehackers.com ) and i pick one of there hack, it was not easy getting the $500 they requested to get me $5,000 to be honest. But, as soon as i got that fee four days later and paid them, in less than 45 minutes, i was at the nearest shop cashing out $5,000 and the journey from then on became smooth, DARK WEB CYBER HACKERS changed my life from a lowlife to a responsible family man because i was willing to take the risk. Thank you so much DARK WEB CYBER HACKERS, am still grateful till today. If you are in this situation right now, or you need urgent money to pay bills, buy a car, buy a house or start up your own business, you could email them on darkwebonlinehackers@gmail.com and you could also Whatsapp or Call/text them on this number +18033921735
