The 16th International Conference on Atomic Layer Deposition (ALD 2016) will be a three-day meeting dedicated to the science and technology of atomic layer controlled deposition of thin films. In every year since 2001, the conference has been held alternately in United States, Europe and Asia, allowing fruitful exchange of ideas, know-how and practices between scientists. This year, the ALD conference will incorporate the Atomic Layer Etching 2016 Workshop, so that delegates at the two events can interact freely. The conference will take place on 24-27 July 2016 at the Convention Centre Dublin, Ireland.
