We’re now much closer to getting 3nm chips on smartphones, but it’s easy to forget that the vast majority of the electronics industry still relies on legacy processes because of their low cost. For this reason, a lot of electronics continue to use the planar 28nm process – a fabrication process that was last seen at the beginning of the last decade. This industry is targeted by Samsung with its newly announced 17nm process node.
The Samsung Foundry Forum 2021 took place yesterday, announcing that Samsung will launch the 3nm GAA process in the first half of 2022, along with the commercial production of 2nm GAA process chips in 2025. A new 17LPV process – 17nm Low Power Value Process (Source: IT Home).
This is basically an innovative version of the 28nm process, the difference being that it combines 28nm BEOL (back-end-offline) and 14nm FEOL (back-end-offline) process. This can significantly reduce consumer costs and improve energy efficiency by leaps and bounds.
The new 17LPV process chip has 43% less area, 39% better performance and 49% better power efficiency compared to the old 28nm process.
While the massive production time for this process has not yet been announced, Samsung says that the first application of the 17LPV will be on camera image signal processors as part of Samsung’s CMOS image sensor portfolio.
Additionally, Samsung integrates the 17LPV process into its high-voltage products for DDIC / display drivers that require back-end high-voltage support with improved logic.
