Hsinchu, July 13 — The race to build the next generation of computer chips is getting curiouser and curiouser. The semiconductor industry is pushing hard toward the 2-nanometer node, a milestone that promises to pack astonishing numbers of transistors onto a sliver of silicon. But how it works, and what comes next, is a story of materials science, new architectures, and a global push for technological sovereignty.
The science behind the 2nm process is a feat of miniaturisation. IBM announced the world’s first 2nm chip design in May 2021, fitting 50 billion transistors onto a fingernail-sized chip.
That is a staggering density, and it points to the fundamental challenge: as features shrink, the behaviour of electricity itself changes. Leakage, heat, and quantum effects become serious obstacles.
Who is building what
Two of the world’s largest chipmakers are locked in competition. TSMC plans to produce 2nm chips at its new fabrication plant in Hsinchu, Taiwan. Intel, meanwhile, aims to achieve its 2nm equivalent — which it calls Intel 20A — by 2024.
Both companies are investing billions in new equipment and processes to make this leap possible. It is not just about shrinking transistors, however.
The industry is also looking beyond traditional silicon. New materials such as gallium nitride (GaN) and silicon carbide (SiC) are gaining traction. These compounds offer higher efficiency at higher voltages, making them ideal for power electronics and radio-frequency applications.
GaN chips, for instance, are already used in fast chargers and 5G base stations, where their ability to switch at high frequencies with less energy loss is a clear advantage.
Beyond the single chip
Intriguingly, the way chips are packaged and connected is evolving just as quickly as the transistors themselves. 3D stacking and chiplet architectures are becoming common. Instead of one large, monolithic die, manufacturers are combining smaller dies — chiplets — and connecting them together. AMD’s EPYC processors already use this approach, stitching together multiple compute cores to create powerful server chips.
This modular strategy allows companies to mix and match different manufacturing processes, potentially saving cost and improving yields. Then there is quantum computing.
While not a direct replacement for classical silicon chips, it could solve problems that are intractable for even the most advanced classical computers. IBM unveiled a 127-qubit quantum processor in 2021. Google claimed quantum supremacy — performing a calculation impossible for a classical machine — in 2019.
These are early steps, but the potential is enormous.
Coordinating the future
Governments are taking notice. The United States, through the CHIPS Act, has funded the National Semiconductor Technology Center (NSTC). This new body will coordinate research into these next-generation technologies, aiming to keep American chip design and manufacturing competitive.
The NSTC will likely play a key role in shepherding 2nm processes, new materials like GaN and SiC, and advanced packaging techniques from the lab into commercial production. What researchers found, and what the industry is now racing to commercialise, is that the path to 2nm is not a straight line.
It is a convergence of multiple innovations: new transistor designs, exotic materials, clever packaging, and entirely new computing paradigms. The next few years will determine which approaches dominate — and which companies and countries lead the way.
