Applied Materials Advances GAA Transistor Tech for AI Chip Scaling

Event summary

  • Applied Materials introduced two new deposition systems, Precision™ Selective Nitride PECVD and Trillium™ ALD, for advanced logic chip manufacturing.
  • The systems are designed to create features at the angstrom scale, crucial for 2nm and beyond Gate-All-Around (GAA) transistors.
  • Precision™ Selective Nitride PECVD preserves shallow trench isolation, while Trillium™ ALD enables precise metal gate stack optimization.
  • Leading logic chipmakers are already adopting these systems in their 2nm and below GAA process nodes.

The big picture

Applied Materials' introduction of these deposition systems underscores the critical role of materials engineering in sustaining Moore's Law and enabling the next generation of AI chips. The shift to GAA transistors and angstrom-scale feature sizes represents a significant increase in manufacturing complexity, requiring specialized equipment and expertise. This development highlights Applied's position as a key enabler of the burgeoning AI infrastructure buildout, but also introduces new dependencies and potential bottlenecks in the semiconductor supply chain.
