Analysis of "Erratum: “History of atomic layer deposition and its relationship with the American Vacuum Society” [J. Vac. Sci. Technol. A 31, 050818 (2013)]"

A correction has been recently published related to a scientific review article on the history of atomic layer deposition (ALD). The correction is entitled "Erratum: “History of atomic layer deposition and its relationship with the American Vacuum Society” [J. Vac. Sci. Technol. A 31, 050818 (2013)]" and it is authored by G. N. Parsons, J. W. Elam,  S. M. George, S. Haukka,  H. Jeon,  W. M. M. Kessels,  M. Leskelä, P. Poodt, M. Ritala, and S. M. Rossnagel. It is published in Journal of Vacuum Science & Technology A 38 (2020) 037001; https://doi.org/10.1116/6.0000143As the title indicates, the article corrects an article published earlier in the same journal, by the same authors: Journal of Vacuum Science & Technology A 31 (2013) 050818; https://doi.org/10.1116/1.4816548.

This blog post analyses, what exactly has changed.

Paragraph corrected describing the early days of the molecular layering origin of ALD

The publication (https://doi.org/10.1116/6.0000143) says that the first two and the last two sentences of the fourth paragraph of Section II, which describes molecular layering, are changed. 

The new, updated paragraph has not been recreated in full. To help the scientific ALD community, I have here attempted to recreate the corrected paragraph.

Farewell to european-ald.net? Future of vph-ald.com?


Related to COST network "MP1402 - Hooking together European research in atomic layer deposition (HERALD)", https://www.cost.eu/actions/MP1402/#tabs|Name:overview, the european-ald.net website appears to no longer exist. When exactly did the website disappear, is not clear to the blog author, but it was not accessible on April 21, 2020 (see Twitter). The Internet archive contains some snapshots from the site, see e.g. https://web.archive.org/web/20190116224057/https://www.european-ald.net/.

The european-ald.net website had lots of useful contents. At the time of writing this blog post, it was unclear to the author if the vanishing is of permanent nature. Websites come with a cost and need maintenance, and it is understandable that they are not forever. If the european-ald.net is permanently gone, it is not the first useful ALD-related site to disappear: an earlier blog post discussed the ending of aldpulse.com (http://aldhistory.blogspot.com/2016/11/aldpulsecom-stops-and-moves-into-history.html). The Final Achievement Report of the HERALD COST action remains accessible on the COST site, https://www.cost.eu/actions/MP1402/#tabs|Name:overview. Thank you once more to Dr. Simon Elliott for setting up and skilfully coordinating the HERALD COST network, and to all who participated. To this blog's author, the HERALD COST network was certainly useful.

Related to the vph-ald.com website that collects together the materials of the Virtual Project on the History of ALD (VPHA), the same principles appear as for any other website.
