A Complete Guide to 5 Nm Processor in Manufacturing Technology

The International Roadmap for Devices and Systems defines the 5 nm process as the MOSFET technology node following the 7 nm node in semiconductor manufacturing. In 2020, Samsung and TSMC will begin volume production of 5 nm chips for companies such as Apple, Marvell, Huawei, and Qualcomm.

The term “5 nanometers” has no relation to any actual physical feature of transistors (such as gate length, metal pitch, or gate pitch). According to the IEEE Standards Association Industry Connection’s 2021 update of the International Roadmap for Devices and Systems, a 5 nm node will have a contacted gate pitch of 51 nanometers and a tightest metal pitch of 30 nanometers. In commercial practice, however, manufacturers of individual microchips commonly use the marketing term “5 nm” to describe a new, enhanced generation of silicon semiconductor chips with higher transistor densities (i.e. a higher degree of miniaturization), increased speed, and lower power consumption compared to the previous 7 nm generation.

5nm Node Density


Newer 5nm designs, like previous manufacturing processes, promise improved power efficiency, faster performance, and overall advancement of CPU technology. But, before we get into that, let’s define a new manufacturing process and transition to a new process node.


Implementation Of 5nm Process

Apple’s A14 Bionic Chip is the first commercially available system on a chip constructed using the 5nm manufacturing process node. It was announced in October 2020, along with the introduction of the iPhone 12 series of smartphones, and is based on the ARM architecture.


Advantages Of The 5nm Manufacturing Process

One advantage of the 5nm manufacturing process is that it allows chipmakers to design and produce chips with a higher density of transistors in a given area, reducing the overall hardware footprint.

A 7nm chip is estimated to have between 95 and 115 million transistors per square millimeter. A 5nm chip, on the other hand, can have a transistor density of 125 to 300 million per square millimeter. These are, of course, estimates. The exact number of transistors or transistor density varies between chips from different manufacturers.

Disadvantage: 5nm chips are new-generation chips that have higher transistor density, better performance, and lower power consumption or improved power efficiency than 12nm and 7nm chips. However, overall performance improvements across chips manufactured on the 5nm process are not the same. A 7nm chip can also outperform.



The improvisation in the 5nm Node helps perform across the chips manufactured with a higher density of transistors. It is necessary for students to study and learn semiconductors manufacturing and there are opportunities in pursuing the be engineering courses that help them to move in direction of creating innovation.
