Thermal Atomic Layer Etch for Logic and Memory Downscaling
April 11 @ 11:30 am - 1:15 pm
[]
Abstract:
As downscaling approaches physical limits, semiconductor devices are evolving into increasingly complex 3D nano-architectures. Fabricating these unprecedented devices in HVM requires precise and selective material deposition & etch methods.
Atomic layer etch (ALE) helps to sculpt these structures by selectively removing materials with angstrom-scale control. By exploiting chemical differences between materials, ALE processes are designed to etch certain exposed materials while minimizing damage to others. ALE can enable scaling boosters such as fully self-aligned via (FSAV), a critical method for logic back end of line (BEOL) downscaling. Vapor-phase thermal ALE can also provide controlled, selective etch in features with high aspect ratio, low critical dimension, or horizontal openings, overcoming the limitations of wet and plasma etches in emerging 3D structures.
This seminar will focus on ALE of metals and metal oxides for logic and DRAM, including process fundamentals, selectivity mechanisms, and thermal ALE processes developed at EMD Electronics
