In the an
earlier post, photos were shared from the
Millennium Technology Prize Gala on May 22, 2018, where
Tuomo Suntola received the prize for
atomic layer deposition technology. This post continues from where the previous post (Feb 10) left, and shares photos from the open lecture that Suntola gave on May 23, 2018, at
Aalto University.

| ALD processing window (or ALD window, in short): Tuomo Suntola explains this concept he developed in the 1980s and which is nowadays widely used in the field of ALD. (Related terminology discussion posts in ALD History Blog: post 1 and post 2.) (Photo: Riikka Puurunen, 23.5.2018) |
 |
| The growth per cycle, GPC (or here: growth rate) does not necessarily have to be constant within the ALD (processing) window, according to Suntola. (Photo: Riikka Puurunen, 23.5.2018) |
 |
| Ten billion transistors per chip! ALD has enabled the continuation of Moore's law and the miniaturization of transistors to the level of today. (Photo: Riikka Puurunen, 23.5.2018) |
 |
| How did it all start? The inventor, Tuomo Suntola, tells his story himself. Some details have been shared in an open-access essay: https://doi.org/10.1002/cvde.201402012. (Photo: Riikka Puurunen, 23.5.2018) |
 |
| Before ALD, Tuomo Suntola had invented the humidity sensor later commercialized by Vaisala (tradename HUMICAP). This invention was an important step towards ALD development, as because of it, Suntola was invited to the Instrumentarium company to "invent something". (Proto: Riikka Puurunen, 23.5.2018) |
 |
| At Instrumentarium, Tuomo Suntola proposed to start making flat panel electroluminescent devices. The board did not understand much of the suggestion - the chairman nevertheless trusted and gave green light to go ahead. (Photo: Riikka Puurunen, 23.5.2018) |
 |
| The Periodic Table of the Elements served as inspiration for Tuomo Suntola to come up with the concept of ALD - originally named Atomic Layer Epitaxy by Suntola. (Photo: Riikka Puurunen, 23.5.2018) |

| Timeline of the electroluminescent devices, the first industrial application of ALD, as shared by the inventor Tuomo Suntola. (Photo: Riikka Puurunen, 23.5.2018) |
 |
| The 1994 Materials Research Society (MRS) conference marked a milestone for ALD in the route towards industrial applications in microelectronics. More details in the open-access essay: https://doi.org/10.1002/cvde.201402012. (Photo: Riikka Puurunen, 23.5.2018) |
