Applied Materials Targets Deeper 3D Chip Structures

Applied Materials introduced Centris Spectral SiN ALD and Producer Selectra Mo Etch for advanced logic and memory production. The systems target deeper and narrower structures used in next-generation AI chips. These designs need tighter material control as manufacturers move beyond flat device layouts.

The semiconductor industry continues to shift toward 3D architectures, including gate-all-around transistors and high-layer-count 3D NAND. These structures create harder deposition and etch requirements. Conventional tools often struggle to process materials evenly from top to bottom.

That weakness can increase variability and reduce device yield. Therefore, Applied Materials aims to improve uniformity in complex structures. The company also links the systems to better performance, energy efficiency, and manufacturability.

Centris Spectral SiN ALD Supports Logic Scaling

Centris Spectral SiN ALD focuses on silicon nitride deposition inside tall and narrow features. Silicon nitride supports passivation, isolation, and patterning spacer steps during chip production. These films must remain strong while forming at low temperatures.

Applied Materials said the system uses high-density microwave plasma technology for more uniform deposition. This approach helps reduce the tradeoff between plasma strength and ion damage. As a result, chipmakers can form dense SiN films inside demanding 3D structures.

The tool also supports logic and DRAM scaling applications. In gate-all-around transistors, it can help form liners for transistor contacts. That process may reduce resistance and capacitance at critical interfaces.

Selectra Mo Etch Addresses 3D NAND Scaling

Producer Selectra Mo Etch focuses on selective molybdenum removal in 3D NAND stacks. Chipmakers use molybdenum for low-resistance wordline metallization. However, those wordlines need precise separation to prevent shorts and reduce unwanted capacitance.

Traditional wet etch methods face limits in tall NAND structures. Liquid chemistries often fail to reach the full depth of deep features. That can create uneven profiles and hurt performance, yield, and scaling.

Selectra Mo Etch uses engineered process control and advanced gas delivery. Applied Materials said the system improves top-to-bottom uniformity across the stack. The company said the tool has already been validated in high-volume manufacturing.

New Tools Align With AI Chip Manufacturing Demand

The launch comes as AI computing increases demand for advanced semiconductor manufacturing tools. Chipmakers need stronger process control as logic and memory designs become more complex. Applied Materials supplies equipment used across several critical production steps.

The company plans to feature the systems around the 2026 IEEE Symposium on VLSI Technology & Circuits. The event will focus on chip advances supporting AI-driven computing. Applied Materials will also host a June 16 panel on logic, memory, packaging, and manufacturing.

AMAT’s share move reflected stronger attention on semiconductor equipment tied to AI infrastructure. The stock closed higher, then added more gains before the market opened. The new systems placed Applied Materials deeper into the industry’s 3D scaling push.
