Apparatus and Methods for Roll-to-Roll (R2R) Plasma Enhanced/Activated Atomic Layer Deposition (PEALD/PAALD)
20230047633 · 2023-02-16 ·

Techniques are disclosed for roll-to-roll (R2R) atomic layer deposition (ALD). R2R ALD is accomplished by arranging precursor nozzles in A/B pairs while a flexible web substrate moves underneath the A/B pairs at a uniform speed. Nozzles A of the A/B pairs continuously flow a precursor A into the process volume of the R2R ALD chamber. The plasma enhanced/activated ALD (PEALD/PAALD) embodiments utilize electron cyclotron rotation (ECR)-enhanced hollow cathode plasma sources (HCPS) where nozzles B flow activated neutrals of precursor B into the process volume. As the flexible web moves in an R2R motion, nucleates from precursor A deposited on the surface of the substrate, and neutrals of precursor B undergo a self-limiting reaction to deposit a single atomically sized ALD film/layer. In this manner, multiple ALD layers may be deposited by each successive A/B pair in a single pass of the web. There is also a heat source underneath the web to further facilitate the ALD reaction, or to support thermal ALD embodiments.
