Samsung vs TSMC: the first 3 nm SoCs are launched

According to the much cited Moore's Law, the technological evolution foresees that the number of transistors in the chips will double every (approximately) 2 years. Since the birth of smartphones, approximately in 2007 with the first iPhone, every 2 years we have started from 45 nm and we have reached 4 nm. The most recent declension of the productive process we find it on SoCs such as Snapdragon 8 Gen and Dimensity 9000, the latest high-end chips from Qualcomm and MediaTek. But as explained in this article, the credit for this technology goes to Samsung and TSMC, that is, the owners of the factories where the chips in question are printed. As a result, both chipmakers and smartphone and PC makers are as if hanging on their lips; and we see it with Samsung, which formalized the start of production of process a 3 nm.

Samsung announces the production of the very first SoCs with 3nm process

After i problems encountered in recent months, Samsung Foundry has kicked off the supply chain that will print its first 3nm SoCs. This milestone was achieved through the implementation of the new GAA architecture (Gate-All-Around). Also known as Multi-Bridge-Channel FET (or MBCFET), this new technology bypasses the limitations of the previous FinFET standard. The transition from the older planar transistors to the newer FinFETs allowed the gate (component of the transistor) to connect to the channel from three different points. With the transition from FinFET to GAAFET and the introduction of nanosheet transistors, the gate has more access points.

This evolution means that the power increases, being able to pass more current, but at the same time it lowers the supply voltage and improves energy efficiency. According to data published by Samsung, pass from 5 nm to 3 nm you will have a performance improvement of 30%, for an reduction of consumption by 50% and a size reduction of 35%.

If Samsung claims to have given away the 3nm manufacturing process, the direct rival TSMC is still back, but what will count will be the final result. Without considering that both companies are already looking to the near future, first a 2 nm and finally a 1 nm, although not there is already no controversy.
