IBM Research alliance produces industry’s first 7nm node test chips; path for next-generation semiconductors

An alliance led by IBM Research has produced the semiconductor industry’s first 7nm node test chips with functioning transistors. The breakthrough, accomplished in partnership with GLOBALFOUNDRIES and Samsung at SUNY Polytechnic Institute’s Colleges of Nanoscale Science and Engineering (SUNY Poly CNSE), could result in the ability to place more than 20 billion transistors on the fingernail-sized chips that power everything from smartphones to spacecraft.

To achieve the higher performance, lower power and scaling benefits promised by 7nm technology, researchers had to bypass conventional semiconductor manufacturing approaches. Among the novel processes and techniques pioneered by the IBM Research alliance were a number of industry-first innovations, most notably Silicon Germanium (SiGe) channel transistors and Extreme Ultraviolet (EUV) lithography integration at multiple levels.

Industry experts consider 7nm technology crucial to meeting the anticipated demands of future cloud computing and Big Data systems, cognitive computing, mobile products and other emerging technologies. Part of IBM’s $3-billion, five-year investment in chip R&D (announced in 2014), this accomplishment was made possible through a public-private partnership with New York State and joint development alliance with GLOBALFOUNDRIES, Samsung, and equipment suppliers. The team is based at SUNY Poly’s NanoTech Complex in Albany.

Microprocessors utilizing 22nm and 14nm technology power today’s servers, cloud data centers and mobile devices, and 10nm technology is well on the way to becoming a mature technology. The IBM Research-led alliance achieved close to 50% area scaling improvements over today’s most advanced technology, introduced SiGe channel material for transistor performance enhancement at 7nm node geometries, process innovations to stack them below 30nm pitch and full integration of EUV lithography at multiple levels. These techniques and scaling could result in at least a 50% power/performance improvement for next generation mainframe and POWER systems that will power the Big Data, cloud and mobile era.

The 7nm node milestone continues IBM’s legacy of historic contributions to silicon and semiconductor innovation. They include the invention or first implementation of the single cell DRAM, the Dennard Scaling Laws, chemically amplified photoresists, copper interconnect wiring, Silicon on Insulator, strained engineering, multi core microprocessors, immersion lithography, high speed SiGe, High-k gate dielectrics, embedded DRAM, 3D chip stacking and Air gap insulators.

IBM and SUNY Poly have built a highly successful, globally recognized partnership at the multi-billion dollar Albany NanoTech Complex, highlighted by the institution’s Center for Semiconductor Research (CSR), a $500-million program that also includes the world’s leading nanoelectronics companies. The CSR is a long-term, multi-phase, joint R&D cooperative program on future computer chip technology. It continues to provide student scholarships and fellowships at the university to help prepare the next generation of nanotechnology scientists, researchers and engineers.



Too bad EV battery technologies are not advancing as fast and as much? If so, we would already have 500++ extended range very low cost BEV?

IBM and partners could direct more resources to develop improved batteries, controls, chargers and automated driving?


IBM indeed is investing huge amont of Money in the Li Air battery. What you fail to understand is that batteries and microelectronics are different field driven by different type of physics and limitation. The progress sin batteries have always been slow whereas progress in microelectronic have always been fast. it is just that it is easier to improve microelectronic than batteries, it is not only a problem of resources.


A-Bombs, H-Bombs, voyages-stations in space and to the moon could be done in 10 years etc., with enough resources.

The same approach could lead to improved batteries (5-5-5 and 10-10-10) unit in the same relative time frame.

Guided automated electric delivery (and war) drones and very low operation cost ($10/hour) electric small airplanes may become better drivers for future improved batteries.
