Samsung Foundry announced that it’s beginning mass production of its first-generation chips on the 3nm node. It’s based on the new GAA (Gate-All-Around) transistor architecture, which is the next step after FinFET.
Compared to 5nm, Samsung’s first-gen 3nm chips can provide up to 23% better performance, up to 45% reduced power consumption, and a 16% reduction in surface area.
Samsung’s second-gen 3nm node will be even more impressive – compared to 5nm, Samsung touts that it will achieve a 50% reduction in power consumption, up to 30% improvement in performance, and a 35% reduction of area.
Samsung is now ahead of TSMC, which is expected to begin mass production of 3nm chips in the second half of the year.
Gate-All-Around (GAA) transistor design allows the foundry to shrink transistors, without hurting their ability to carry current. The GAAFET design used in the 3nm node is the MBCFET flavor shown in the image below.
