The push toward ever more complex 3D device architectures is creating new demands on materials and process integration. ASM International is using this shift to underline that continued scaling is no longer only a lithography issue, but also a question of how well materials and fabrication steps can support stacked and three-dimensional structures.
As devices become more intricate in the vertical dimension, the process window for materials narrows. Layers must be formed, modified, and combined in ways that preserve device function while fitting the tighter geometries of 3D designs. That makes materials behavior and process compatibility central issues rather than secondary considerations.
The focus on 3D scaling also reflects a broader change in semiconductor manufacturing priorities. Instead of relying solely on patterning advances, the industry must address how deposition, interface control, and subsequent process steps interact inside increasingly dense structures. In this context, the material system itself becomes a key enabler of further device complexity.
ASM International’s message is straightforward: as scaling continues into the third dimension, the requirements on materials and processes rise in parallel. The technical challenge is not just making smaller features, but ensuring that the full stack of materials and steps can support the next generation of complex device structures.
