Regardless of its incapacity to acquire an excessive ultraviolet lithography machine (U.S. and Dutch sanctions, you recognize), China’s SMIC is in third place and was simply 3.3 share factors behind Samsung Foundry throughout the third quarter of this 12 months. That compares to the 5.8% lead Samsung Foundry held over SMIC throughout the second quarter of 2024.
Although Samsung Foundry was the primary to make use of Gate-all-around (GAA) transistors with its 3nm node (TSMC will begin utilizing GAA subsequent 12 months with its 2nm manufacturing), Samsung Foundry hasn’t seen a lot demand for its providers at 3nm. GAA transistors use vertically positioned horizontal nanosheets permitting the gate to cowl the channel on all 4 sides. This reduces present leakage and improves the drive present leading to chips with enhanced efficiency and higher power effectivity.

Whereas it appears like a plan, whether or not each elements may be completed just isn’t recognized. And even when each elements may be performed, it nonetheless is not recognized whether or not this plan could make Samsung Foundry extra of a menace to TSMC whereas permitting it to tug away from SMIC.
