The webinar was given by Topias Jussila, Doctoral Researcher, Aalto University, Finland. Let's explore how ALD and MLD are shaping the future of materials at the nanoscale.

The Emergence of MLD

Molecular Layer Deposition, though a relative newcomer compared to ALD, has quickly garnered attention for its unique capabilities. MLD, which operates on the principle of sequential molecular layering, offers a versatile platform for creating hybrid materials with tailored properties. The webinar expertly delineated the different types of MLD, such as metal-aliphatics, metal-aromatics, and inorganic-organic multilayers, each presenting its distinct advantages in material fabrication.

 


Synergy of ALD and MLD

The fusion of ALD with MLD emerged as a focal point of discussion. This combination enhances the material properties, allowing for precise control at the nanoscale. The synergy of ALD and MLD opens doors to innovative applications, particularly in microelectronics and nanotechnology, by creating materials with unprecedented electrical, optical, and mechanical properties.

 


Applications That Reshape Industries

The practical applications of MLD and ALD-MLD are vast and varied. Key areas include:

Flexible Barrier Layers: MLD is particularly effective in creating ultra-thin, flexible barrier layers that are impermeable to gases and moisture. This is crucial for applications like organic light-emitting diode (OLED) displays and flexible electronics, where moisture and oxygen can degrade the performance of the devices.

Encapsulation: MLD provides an excellent method for encapsulating sensitive components, protecting them from environmental factors without compromising their functionality.

Photocatalysis: MLD materials are used in photocatalysis applications, which are important in environmental remediation and energy conversion technologies.

Electronics and Semiconductors: The combination of MLD with ALD is particularly advantageous in the electronics and semiconductor industries. It enables the precise deposition of thin films with tailored electrical and optical properties, crucial for advanced microelectronics and photonics.

Biomedical Applications: The versatility of MLD and ALD-MLD coatings also finds applications in the biomedical field, such as in drug delivery systems and bioimaging, where biocompatibility and controlled interactions with biological environments are essential.

Industrialization and Future Outlook

As for the industrialization of MLD, it is a relatively newer field compared to ALD. While ALD has been widely industrialized, particularly in the semiconductor industry, MLD is still primarily in the research and development stage, with growing interest in transitioning to industrial applications. The unique capabilities of MLD in creating organic-inorganic hybrid materials are driving research and potential industrial applications, but widespread industrial adoption might still be in progress.

Conclusion

The ALD and MLD webinar served as a beacon of knowledge, shedding light on the latest advancements and future prospects of these technologies. As we step into an era where material science plays a critical role in technological advancements, the insights from this webinar not only educate but also inspire further exploration and innovation in the field. The future of material science, undoubtedly, holds exciting possibilities, with ALD and MLD at its forefront.


Background: Topias Jussila is a second year PhD student at the Department of Chemistry and Materials Science, Aalto University, Finland. Topias carried out his Bachelor’s degree in Chemistry at the University of Helsinki and Master’s degree in Functional Materials at Aalto University. For the past two years, Topias has worked intensively with atomic layer deposition (ALD) and molecular layer deposition (MLD) with a target to develop novel thin film materials with advanced functional properties, having the main focus in iron-based inorganic and inorganic-organic materials. In addition to deposition process development, he has employed a wide range of thin film characterization methods to study the composition, structure, and functional properties of the thin films.

Picosun accelerates growth with a notable Finnish investment

ESPOO, Finland, June 28, 2019 -- Finnish investors make significant investments in Picosun, a manufacturer of ALD equipment, increasing the company's share capital by 12 million euros. New investors are CapMan Growth fund, Finnish Industry Investment Oy, and Risto Siilasmaa's First Fellow Partners.

Earlier investors in Picosun - Hannu Turunen, and R.Ruth Oy - also make add-on investments in the company, in addition to the company's Board members Prof. Jorma Routti and Dr. Tech. Tuomo Suntola. 


"We are already the world's number one manufacturers of research and other specialised equipment within the ALD field, but we aim to achieve a leading position also in other large ALD production equipment. We are determinedly moving in this direction," says Kustaa Poutiainen, Chairman of the Board at Picosun.

The family office of Kustaa Poutiainen, Stephen Industries Oy, remains the majority investor after the funding round.

ALD, or Atomic Layer Deposition, is a Finnish technology developed by Dr. Tech. Tuomo Suntola, who has been awarded the Millennium Technology Prize. The technology enables the creation of precise films with a thickness of less than a nanometer, which is a prerequisite for the functionality of modern electronics. New applications for ALD are constantly found in e.g. medical technology.

"ALD technology is one of the most significant Finnish inventions and we are proud to participate in the acceleration of Picosun's growth and internationalisation. ALD technology is present in many everyday devices and processes and according to our estimates, the market is growing by almost 30 percent per year in the next five years. Picosun has already proven to be a leading performer in certain industrial verticals and has achieved global recognition. We want to be a part of taking the development to the next level," says Juha Mikkola, Managing Partner of CapMan Growth.

"We entertained several finance options in order to deliver on our growth strategy, but the current outcome was preferred by far. ALD is one of the most influential success stories in Finnish technology. We are really pleased to be able to strengthen our position globally together with experienced Finnish owners," concludes Poutiainen.

Picosun's turnover exceeded 26 million euros last financial year and the company employs more than 100 persons globally. More than 95 percent of the production goes to export.
