Applied Materials unveils two deposition systems for sub-2 nm GAA processes
Applied Materials on Monday unveiled two deposition systems tailored for sub-2 nanometre gate-all-around (GAA) transistor processes. The company said GAA transistor fabrication requires more than 500 process steps to build internal 3D structures, with many steps demanding near-atomic tolerances. One system uses selective bottom-up silicon nitride deposition to protect shallow trench isolation structures and reduce parasitic capacitance. The other controls metal gate stacks with atomic-level uniformity and integrates multiple metal deposition steps on one platform.

Chipmetrics targets South Korea as 3D NAND heads toward 1,000 layers
Finnish semiconductor metrology startup Chipmetrics is targeting South Korea as 3D NAND stacking moves beyond 300 layers toward 1,000. It aims to measure thin-film quality inside deep, narrow holes with a method it says is hundreds of times faster than conventional cross-section TEM analysis. CEO Mikko Utriainen said precise measurement will be key as aspect ratios rise. CTO Feng Gao said fabs often measure only planar uniformity, not conformality in 3D structures.

Applied Materials unveils 2-nanometer performance boost, says AI chip energy efficiency improved 10,000-fold
Applied Materials unveiled materials innovation technologies to improve GAA transistor performance and energy efficiency in sub-2-nanometer processes. At a Seoul media briefing, Kevin Moraes said energy efficiency improved 10,000-fold over the past 15 years and needs another 10,000-fold gain over the next 15. The company introduced Viva radical processing, Sym3 Z Magnum etching and Spectral molybdenum ALD systems, which it said are being used by multiple leading foundry and logic manufacturers.
