The UK Centre for Process Innovation (CPI) and Beneq signed a collaboration agreement to commercialise atomic layer deposition (ALD) technologies for printed electronics applications.

CPI OLED/OPV prototype line photoCPI OLED production line

Beneq and the CPI will create an open access environment for companies to develop ultra barrier solutions in areas such as photovoltaics, OLEDs, microelectronics and sensors. The CPI recently installed two ALD deposition tools from Beneq for the development of conformal nano-scale coatings - one batch ALD tool and one state of the art roll-to-roll ALD (R2R ALD) system. In particular the roll-to-roll ALD tool processing technology will be actively developed between the two companies.

CPI's current OLED system supports both small evaporized and soluble OLED materials. Their pilot production line uses slot die technology to allow the coating of substrates (4", 6" or 8" in size) in a highly repeatable and reproducible manner with a uniform film thickness of under 50 nm.

In October 2013 we interviewed Beneq's technical sales director who explains the company's ALD-based OLED encapsulation technology.
