Picosun Presents Continuous ALD for Moisture and Oxygen Barriers
ESPOO, Finland, March 4, 2013 /PRNewswire/ --
Picosun Oy, leading Atomic Layer Deposition (ALD) equipment manufacturer, and VTT
Technical Research Centre of Finland report notable progress in continuous ALD technology.
The water vapour and oxygen transmission rates measured from polymer films coated with
thin ALD Al2O3 layer in Picosun's new roll-to-roll ALD deposition chamber were on a par
with the values obtained with similar coating in a batch ALD process, thus proving
Picosun's design for continuous ALD solution the frontrunner in producing barrier films on
flexible substrates - one of the most sought-after ALD applications of today.
ALD is well suited technique for depositing thin inorganic coatings onto
temperature-sensitive and/or flexible materials such as plastic films, metal foils and/or
biomaterial sheets. In this study, thin and uniform Al2O3 coatings were deposited onto
different types of polymer films at relatively low temperature of 100 degree(s)C by
employing both the batch and the roll-to-roll ALD techniques at VTT facilities. Water
vapor and oxygen transmission rates (WVTR and OTR) were measured from coated and
non-coated films at relative humidity of 50 % and temperature of 23 degree(s)C. Both WVTR
and OTR values of coated samples were 100-1000 times lower compared to uncoated sample
values, and with several polymer materials even lower than the measurement equipment's
detection limit.
"The excellent moisture and oxygen barrier results obtained with our continuous ALD
technique prove again the superiority of our equipment design. Upscaling the roll-to-roll
ALD method to high volume manufacturing will establish Picosun's leading position in
several new, strategically important market areas," summarizes Juhana Kostamo, Managing
Director of Picosun.
Picosun Oy is a Finland-based, globally operating manufacturer of state-of-the-art ALD
systems, representing continuity to almost four decades of pioneering, exclusive and
groundbreaking ALD reactor design and manufacturing. Today, PICOSUN(TM) ALD systems are in
daily production and R&D use in numerous prominent industries and research organizations
across the world. http://www.picosun.com
VTT Technical Research Centre of Finland is the leading multitechnological applied
research organization in Northern Europe. VTT creates new technology and science-based
innovations in co-operation with domestic and foreign partners. VTT's turnover is EUR 290
million and its personnel totals 3,100. http://www.vtt.fi
