If you are one of those who are paranoid about their phone batteries dying in the middle of the day, there is some great news.
IBM and Samsung Electronics jointly announced a breakthrough in semiconductor design utilizing a new vertical transistor architecture that could lead to your cell phones getting charged for a week instead of hours.
The Vertical Transport Field Effect Transistors (VTFET) is a new approach to stacking transistors vertically instead of horizontally. It has the potential to reduce energy usage by 85% compared to a scaled fin field-effect transistor (finFET).
Moore’s Law, the principle that the number of transistors incorporated in a densely populated IC chip will approximately double every two years, is quickly nearing what is considered insurmountable barriers. Simply put, as more and more transistors are crammed into a finite area, engineers are running out of space.
Historically, transistors have been built to lie flat upon the surface of a semiconductor, with the electric current flowing laterally, or side-to-side, through them. With the new VTFET, IBM and Samsung have successfully implemented transistors that are built perpendicular to the surface of the chip with a vertical, or up-and-down, current flow.
The new vertical transistor breakthrough could help the semiconductor industry continue its relentless journey to deliver significant improvements, including:
- Potential device architecture that enables semiconductor device scaling to continue beyond nanosheet.
- Cell phone batteries that could go over a week without being charged, instead of days.
- Energy-intensive processes, such as crypto mining operations and data encryption, could require significantly less energy and have a smaller carbon footprint.
- Continued expansion of the Internet of Things (IoT) and edge devices with lower energy needs, allowing them to operate in more diverse environments like ocean buoys, autonomous vehicles, and spacecraft.
“Today’s technology announcement is about challenging convention and rethinking how we continue to advance society and deliver innovations that improve life, business and reduce our environmental impact,” said Dr. Mukesh Khare, Vice President, Hybrid Cloud, and Systems, IBM Research.
“Given the constraints, the industry is currently facing along multiple fronts, IBM and Samsung are demonstrating our commitment to joint innovation in semiconductor design and a shared pursuit of what we call ‘hard tech’.”
The VTFET process addresses many barriers to performance and limitations to extend Moore’s Law as chip designers attempt to pack more transistors into a fixed space. It also influences the contact points for the transistors, allowing for greater current flow with less wasted energy.
Overall, the new design aims to deliver a two times improvement in performance or an 85% reduction in energy use as compared to scaled finFET alternatives.
The global semiconductor shortage has highlighted the critical role of investment in chip research and development and the importance of chips in everything from computing, to appliances, to communication devices, transportation systems, and critical infrastructure.
This collaborative approach to innovation makes the Albany Nanotech Complex a world-leading ecosystem for semiconductor research and creates a strong innovation pipeline, helping to address manufacturing demands and accelerate the growth of the global chip industry.
Recently, IBM announced the 2 nm chip technology breakthrough which will allow a chip to fit up to 50 billion transistors in a space the size of a fingernail. VTFET innovation focuses on a whole new dimension, which offers a pathway to the continuation of Moore’s Law.
The companies also announced that Samsung will manufacture IBM’s chips at the 5 nm node. These chips are anticipated to be used in IBM’s server platforms. This follows the announcement in 2018 that Samsung would manufacture IBM’s 7 nm chips, which became available in the IBM Power10 family of servers earlier this year. The IBM Telum processor, also revealed earlier this year, is similarly manufactured by Samsung using IBM’s designs.
