The AVS ALD ALE 2024 conference in Helsinki, Finland, which took place from August 4-7, 2024, attracted significant attention number of delegates (number still pending) and reporting on social media among professionals in the field of atomic layer deposition and etching. Participants and companies highlighted key moments and innovations presented during the conference.
One of the major highlights shared on platforms like X/Twitter was the celebration of the 50th anniversary of Atomic Layer Deposition (ALD), with special recognition given to Dr. Tuomo Suntola, the pioneer of ALD technology. His opening remarks were highly anticipated and well-received, marking a significant milestone in the field.

Additionally, the leading ALD & ALE companies showcased their latest advancements. For example, Lotus Applied Technology drew attention for their presentation on ultra-high-speed ALD film growth, achieving deposition rates of 30 Å/second while maintaining film uniformity. This breakthrough was a trending topic among attendees, reflecting the ongoing innovation in the ALD sector.
Lotus Applied Technology reported: The research on ultra-high-speed spatial Plasma-Enhanced Atomic Layer Deposition (PEALD) introduces a novel approach to separating ALD half-reactions by leveraging a unique plasma-based mechanism. Instead of traditional differential flow and pumping, the process utilizes a gas shroud surrounding the plasma electrode, which facilitates the neutralization of oxidation radicals, preventing interaction with metal precursor vapors within the reactor. This method effectively separates the reactive species and allows for high deposition rates, achieving coating speeds over 25 angstroms per second for SiO₂ films. The process also includes innovations to reduce ozone byproducts, such as using carbon dioxide as the plasma gas and applying an active catalyst in the exhaust path (Lotus Applied Technology | Home).
At the end the AVS ALD ALE 2025 was presented: The AVS 25th International Conference on Atomic Layer Deposition (ALD 2025) featuring the 12th International Atomic Layer Etching Workshop (ALE 2025) will be a three-day meeting dedicated to the science and technology of atomic layer controlled deposition of thin films and atomic layer etching. Since 2001, the ALD conference has been held alternately in the United States, Europe and Asia, allowing fruitful exchange of ideas, know-how and practices between scientists. The conference will take place Sunday, June 22-Wednesday, June 25, 2025, at the International Convention Center Jeju (ICC Jeju), Jeju Island, South Korea. ald2025 (avs.org)
