For processes used to make processors, the smaller the transistor size, the larger the number of transistors. For example, the first generation iPhone used the 45nm process SoC. While the current top chipsets, including Snapdragon 855 are manufactured on a 7nm process. And with the use of ultraviolet etching technology (EUV), chip manufacturers can design more accurately the layout of integrated circuits (ICs) to further improve performance.
TSMC, a multi-chip manufacturer found in today’s smartphones, plans to mass produce the first 5nm chips in Q1 / 2020. Preliminary information indicates that the number of transistors will increase by 1.8 times compared to 7nm chips, with a 15% increase in performance.
Recent reports show that Samsung will use the Snapdragon 865 running on the EU 7nm process, which would be disadvantageous if the iPhone 2020 uses TSMC’s 5nm chip.
However, experts say it will be difficult to make the chip process smaller, 2nm is probably limited by transistors operating in binary mode (0 and 1) so when they are too small, they will no longer be available. distinguish each other’s state. So the solution to this is that companies need to have an optimized AI system to hope to compensate for hardware that has reached its limit.
Innovation does not stop here, however, because TSMC is already working on assembling 3nm processor production lines in Taiwan’s Hsinchu region, scheduled to start somewhere in 2020. Later, the 2 nm processors will be built in the same city.
