Baltic ALD 2016, St. Petersburg: travel notes by Puurunen

Updated October 9, 2016
The 14th International Baltic Conference on Atomic Layer Deposition (Baltic ALD 2016, was organized in St. Petersburg, Russia, on October 3-4, 2016.

The conference consisted of one day of invited lectures and one day of contributed talks and posters. The conference venue was Solo Sokos Hotel Palace Bridge (V.o. Birzhevoi Pereulok 2-4, St. Petersburg, 199004) on the Vasilievsky Island. A get-together event was organized on October 2, 2016. The conference chairman was Prof. Vladimir Kutuzov, the rector of St. Petersburg Electrotechnical University"LETI" and the chairman of the International Advisory Board was Prof. Markku Leskelä from the University of Helsinki. Central local organizers were Prof. Nikolay Egorov and Prof. Alexey Ivanov from LETI. Roughly forty persons participated at the conference. I (Riikka Puurunen) had the pleasure to participate at BALD 2016 both as an invited speaker and as a regular contributor. This was the third time that I participated at a Baltic ALD conference; earlier, I have attended the Baltic ALD of 2014 in Helsinki and of 2015 in Tartu (travel report).
The opening words of the conference were delivered by Vladimir Kutuzov and Markku Leskelä. Then followed the talks by invited speakers: Riikka Puurunen (VTT Technical Research Centre of Finland), Victor Drozd (St. Petersburg State University, Russia), Mikko Ritala (University of Helsinki, Finland), Emma Salmi (Beneq, Finland), Erwin Kessels (Eindhoven University of Technology, Netherlands), Tobias Törndahl (Uppsala University, Sweden), Andrey Markeev (Moscow Instititute of Physics and Technology, Russia) and Victor Luchinin (St. Petersburg Electrotechnical University “LETI”, Russia). According to the programme, there were 27 contributed talks and 22 posters. 

This is the first time that a meeting in the “Baltic ALD” conference series has been organized in Russia. As told by Markku Leskelä, the Baltic ALD conference series started as a local meeting between Helsinki University of Technology and Tartu University; the first meeting was organized in 1991. Conferences have been organized somewhat irregularly, the typical time between consecutive conferences having been two years (but sometimes just one, and once even five years).  

At this meeting, the "final presentation" of the Virtual Project on the History of ALD (VPHA) was given. VPHA has been active since 2013 and the items listed in the Publication Plan are now approximately completed (this presentation was #12). The slides of the presentation can be accessed at: and a live (partial) record at: The VPHA reading work still continues: there are still ~300 “comments” missing and more volunteers are welcome to join the work (several joined at the conference). ALD-history-evolving-file will stay as a growing reference file for early ALD works in the future, too.

The conference was interesting not only because of its historical significance but also because of its scientific contents. As stated by Markku Leskelä in his closing words, this meeting was “a good member in the Baltic ALD series.” Hopefully, the international ALD community can meet in St. Petersburg again in the future.

Below, you find some photos from the conference. Most of the photos have been taken by myself. Some photos are from Tomi Iivonen, Kaupo Kukli, and Fabio Grillo, and I am grateful for them all for allowing me to publish their photos in this blog post.

On Tuesday evening, I went (with Tobias Törndahl) for dinner in the centre. Literary Cafe on Nevski Prospect was fully reserved. Next time in St. Petersburg, need to make a reservation!  

On Wednesday morning, we visited Prof. Anatoly Malygin with Ana Gomes Silva. Malygin has been a central collaborator in the VPHA.  Photo was kindly taken by Malygin's student Ivan Bodalyov.
