Virtual issue of Chemistry of Materials in Honor of Professor Markku Leskelä

A "virtual issue" - an electronic collection of articles centered on a topic - was published by Chemistry of Materials in July 2018 to celebrate the influential career of professor Markku Leskelä at the verge of his retirement. The virtual issue was published just in time for the ALD 2018 conference, so the conference could celebrate at the same time the 2018 Millennium Technology Prize for Dr. Tuomo Suntola as well as the virtual issue of Prof Leskelä. 

The full virtual issue can be accessed through: https://pubs.acs.org/page/vi/MarkkuLeskela.html. It contains scientific articles published by Leskelä, as well as scientific articles influenced by Leskelä's works, in different journals by ACS. 

A related editorial by his close colleague and first student, Prof. Mikko Ritala and by Chem. Mater. editors is accessible at: http://dx.doi.org/10.1021/acs.chemmater.8b02742, entitled "In Honor of Professor Markku Leskelä."

VPHA website updated with ECS Transactions article info

The VPHA website, http://vph-ald.com, has been on July 28, 2018 updated with info of the ECS Transactions article in press:
  • Proceedings: R. L. Puurunen, "Learnings from an Open Science Effort: Virtual Project on the History of ALD", ECS Transactions, in press (2018). Open access preprint, DOI: 10.1149/osf.io/exyv3.

As the international ALD 2018 conference in Korea starts on July 29, 2018, it is good to spread the message that VPHA is still on-going and more volunteers are welcome to join. As communicated in the VPHA status update in May 2018, the plan is to produce jointly one more brief concluding review article from within VPHA. (Previous publications are listed in the Publication Plan here; the review now in question belongs to Item 10.) The articles produced earlier from within VPHA have become impactful within the field of ALD what comes to citations and other attention (see e.g. Altmetrics for the "ALE essay"). The last review is expected to be impactful, too.

The question that started the Virtual Project on the History of ALD

I noticed that the discussion chain, which initiated the Virtual Project on the History of ALD, is still accessible in LinkedIn. Here, I copy the first post, which was a question by myself. Markedly, there in total 26 items of discussion at the moment (and one "like"). To my knowledge, the post was written on May 6, 2013. Screen capture of the post, full copy of the text below. (I was not a professor at Aalto University then, but a senior researcher at VTT.) Link to the discussion chain, which is still open: https://www.linkedin.com/groups/1885076/1885076-238399494.

Dr. Suntola thanks the community for support and shares honor for the 2018 Millennium Technology Prize

Upon request, I transmit two messages from Dr. Tuomo Suntola, the awardee of the 2018 Millennium Technology Prize, to the ALD community.


First, Dr. Tuomo Suntola, who has had a busy week after receiving the prize on May 22, 2018, would like to thank the community for the broad support for the 2018 Millennium Technology Prize. This support, seen as forty supporting letters accompanying the nomination letter, has evidently had a significant role in strengthening the nomination. It was the pleasure and honour of the undersigned to spread information of the coming nomination at conferences in 2017 and to collect the supporting letters from esteemed scientists and technologists from various organizations around the world. In the words of Dr. Suntola in his speech at the 2018 Millennium Technology Prize ceremony:

” …  also, my sincere thanks go to the materials research and semiconductor processing community for the broad support behind the nomination.”

Second, Dr. Tuomo Suntola wishes that the prize will be experienced as credit for all actors in the field. Again, from his speech at the ceremony:

” … In the long run, I like to share the honor of the Millennium prize with all my colleagues having worked with me for the technology, the companies hosting and financing the development, and the co-operating universities and funding organizations supported the work. I like to thank all parties for the confidence and patience in getting through times when the goal looked distant. Finally, my special thanks go to the thousands of scientists and engineers who, finally, have made the technology a global success and an important part of our everyday life.”

It is an honour for myself and for the ALD History Blog as publication platform to transmit these messages from Dr. Tuomo Suntola to the community.

Espoo, Finland, May 27, 2018,

Congratulations Dr. Tuomo Suntola for the 2018 Millennium Technology Prize!

Dr. Tuomo Suntola has been awarded the 2018 Millennium Technology Prize for the Atomic Layer Deposition (ALD) innovation. Warmest congratulations!   


In the view of the undersigned, Virtual Project on the History of ALD (VPHA, http://vph-ald.com/) has been crucial for realizing the prize this year. Drafting the nomination letter was a natural continuation of the VPHA ALD history activities. The scientific publications created in VPHA describe the history of ALD in a balanced way and thus directly supported the prize. Wikipedia updates have been important in spreading the information beyond the immediate scientific ALD community. Thank you to all who have been involved in these voluntary works and for the numerous supporting letters provided!
  • List of three scientific articles on the history of ALD, created within ALD, below.
  • A longer list of ALD-history-related publications is available at http://vph-ald.com/ALD-history-publications.html
  • Previous ALD History Blog posts related to the 2018 Millennium Technology Prize here.
  • Some photos of the events on May 22 and 23 at the end of the post. 

Dr. Tuomo Suntola deserves the prize extremely well for his breakthrough pioneering accomplishments in ALD technology. Suntola has always supported the ALD history activities by the undersigned; likewise, it has been great to feel the widespread support in the international ALD community for the prize to Suntola. I hope that the prize can still further unite the ALD community and spread understanding of this enabling "hidden technology" to the general public.

Congratulations Tuomo Suntola; congratulations the rest of us in the ALD community; let us enjoy this moment!
