IBM unveils world’s first 5nm chip. IBM, working with Samsung and GlobalFoundries, has revealed the world’s first 5nm silicon chip. The 5nm IBM chip is prominent in using horizontal gate-all-around (GAA) transistors and extreme ultraviolet (EUV) lithography. It will provide better performance, better power management and increased density using smaller transistors.
GAAFET is developed part of tri-gate finFETs that can be used for most 22nm and below chip designs. But it will possibly run out of condensation at around 7nm. GAAFETs may go all the way down to 3nm, especially when combined with EUV.

The main focus was on decreasing the size for increasing the power on a 2D plane, so finFETs solved the problem by creating 3D plane. Somewhat than use of current FinFET architecture, IBM has been exploring stacked nanosheet transistors, assisted by a technique that allows it to adjust the chip’s design for improved power and performance in ways that FinFET can’t.
In the final analysis, IBM has created a GAAFET model with a new chip that allows for consistency, better performance, and can even be further scaled down to fit into smaller spaces. The main advantage is that chip can further be trimmed down into smaller size. IBM 5nm chip size is the most ideal size for the finest performance.
