Samsung Foundry might have had an enormous benefit over TSMC on the 3nm course of node. That is as a result of, in contrast to TSMC, Samsung Foundry determined to make use of Gate-All-Round (GAA) transistors for its 3nm manufacturing. These transistors use vertically positioned horizontal nanosheets to encompass the channel on all 4 sides decreasing present leaks and enhancing the drive present. In consequence, SoCs made with GAA transistors sometimes supply improved efficiency with diminished energy consumption.
This could have given Samsung Foundry an edge on the presently used second-generation 3nm node since main foundry TSMC nonetheless makes use of FinFET transistors which encompass the channel on solely three sides. TSMC will change to GAA subsequent 12 months when it begins mass manufacturing of its 2nm chips. However there may be one fundamental motive why TSMC continues to take enterprise from Samsung Foundry and that’s associated to the latter’s extraordinarily poor yield.

The yield is the share of excellent chips that go high quality management divided by the utmost variety of chips that might be produced from a single silicon wafer. For its 3nm GAA manufacturing Samsung reportedly anticipated yields to hit 70% and for the primary technology of the 3nm node (aka SF3E-3GAE) the yield was between 50% and 60% which was simply shy for the 70% that may get fabless chip designers to decide on Samsung Foundry to construct their parts.
With its 3nm yields terribly low, Samsung is supposedly transferring forward and is engaged on its 2nm node. A earlier rumor known as for Samsung Foundry to develop and manufacture an unnamed Exynos chipset on the SF2P 2nm node. The chip is codenamed ‘Ulysses,’ and it might debut on one of many Galaxy S27 fashions launched in 2027.
