5NM With 30 Billion Transistors Developed By IBM

Moore’s Law is pretty clear when it comes to the implications of limited space in the tech industry. However, there appears to be quite some time before developers hit that wall since IBM just made history with its new chip. It’s the thickness of a fingernail and holds 30 billion transistors, making it the first in the world.

As Forbes reports, IBM created the world’s first 7nm chip two years ago. Now, the company is announcing that it managed to create a 5nm version. What really makes this new chip noteworthy is how densely packed it is, even compared to the 7nm version. That chip only had 20 billion, while the new one has 10 billion more than that.

According to the company, the density of the transistors makes the transport of information between them a lot faster. This means that the 5nm chip gets a performance boost of 40 percent. It also gets better power efficiency at 75 percent more.

In terms of how IBM managed to create the chip, it apparently used a new kind of transistor called “stacked silicon nanosheets.” This allows the company to pack the transistors as densely as it has managed to. As IBM Research VP of semiconductor tech research, Mukesh Khare says this development was important because the FinFET design is no longer scalable.

On the other hand, IBM’s new method called gate-all-around field effect transistors (GAAFETs) can go as thin as 3nm, Futurism reports. This means that companies can buy time and keep Moore’s Law at bay until someone can find a better method of extending technological development.

As to why developers are making thinner and thinner chips, in the first place, the answer has to do with speed and size. Smaller, denser chips mean faster and more efficient performance. This makes them perfect for work with high-performance demands.
