We are the trusted partner in your ALD journey from day one until the start of your production – and beyond. ALD is what we do. And we do it with deep know-how and passion to ensure your safe operations and lower total cost of ownership. Let’s innovate together.

    We have been part of the ALD community from the very start. Dr. Tuomo Suntola, who invented and patented the ALD method for industrial purposes in Finland in 1974, was a Member of Picosun Board of Directors for several years.

    We are a global company based in Espoo, Finland. Picosun has subsidiaries in Germany, USA, Singapore, Japan, South Korea, mainland China and Taiwan, offices in India and France, and a global sales and support network with distributors and representatives in over 30 countries.

    Today, PICOSUN® ALD tools are in daily production use at several leading industries from the largest manufacturers to small challengers, and high-level research organizations across the world.

    In June 2022 Picosun became part of Applied Materials, Inc.

    Picosun’s values

    Our company values reflect who we are

    To put it simply, they define what kind of behavior and attitude we appreciate, and how we act towards our customers, colleagues, and other stakeholders each and every day.

    At Picosun we are committed to Customer Focus, Innovation, Collaboration, Accountability, and Care.


    Picosun’s entire ethos revolves around our customers – without them, we are nothing. Our team of dedicated professionals push out all the stops to rapidly create precisely tailored, high-quality solutions that exceed our customers’ specific needs, engaging in continuous dialogue and making sure that we keep all of our promises throughout the lifetime of our customer solutions. Only by ensuring our Customers´ success can we succeed. Our aim is always to be the best – from the little details all the way to the bigger picture!​​​​​​​


    Innovation is at the heart of what we do at Picosun. We were involved in inventing ALD technology, but we are never happy to just rest on our laurels. We have continued to break new ground in ALD technology, often being first with innovative solutions that disrupt the markets, and we own a number of vital patents in the field. We don’t just make tools. We are problem-solvers, and our innovative spirit drives our internal processes, working methods and practices, as well as our complete ALD solutions and the related tools. We are still continually working at the frontiers of ALD, striving to engage our creativity to push the technology further for the benefit of our customers – and their customers.​​​​​​​


    At Picosun, we live and breathe collaboration. We know we can only achieve our goals when we are all pulling in the same direction. Collaboration is vital to success in a demanding market. In our projects, we share information, we listen, and we help each other, providing support and constructive feedback. The best and most innovative solutions come from being truly open to other people’s ideas. We take the same approach to working with our customers, research partners, and other stakeholders, too. We have repeatedly proved that we are a trustworthy and reliable partner, and we show trust in others as well.


    We want to produce solutions that we can be truly proud of. At Picosun, we strive to be the best we can possibly be. We are true professionals, with reliable working methods and a team of talented people who genuinely care. We are honest and trustworthy – when we make a promise, we keep it. If we encounter a problem, we don’t shy away from it – we find a solution. We shoulder our responsibilities, and we take ownership rather than run away. Trust is core to what we do at Picosun, and we always do whatever it takes to win our customers’ trust.


    We work hard to create an atmosphere where everybody is valued equally. Everyone at Picosun is a member of one and the same team. We are supportive and encouraging, nurturing each other’s development as professionals, and as people. We respect each other, and we value diversity, differing viewpoints and varied opinions. This is not just true within our company – we take the same attitude and approach into our work with customers and other stakeholders, too.  We recognize our social responsibilities, and we live up to them. Our caring attitude is clearly visible in our high ethical standards, our social responsibility, our environmental awareness and responsibility, and our focus on health and safety.
