The Centre for Process Innovation CPI

The Centre for Process Innovation Opens external link in new window(CPI) is a UK based technology innovation centre.  At CPI’s National Printable Electronics Centre, we offer world class, open access capability for the scale up and commercialisation of new, innovative printed electronic products and applications.


CPI Barrier and Vacuum Encapsulation

High performance large area coatings and processes


CPI has extensive experience in the deposition and characterisation of barrier layers. We offer access to a wide variety of thin-film deposition systems including batch and roll to roll atomic layer deposition (ALD), roll to roll sputtering and also a range of other sputtering and vacuum coating technologies.


CPI is engaged in a wide range of projects initially focussing on thin-film barrier technology for long-lasting and efficient flexible electronic devices. Further developments, up to pilot scale, are targeted in printable electronics applications in the display, photovoltaics, lighting and sensor fields with both rigid and flexible substrates utilising batch and processing techniques.


CPI’s equipment includes:

                        Roll to roll atomic layer deposition

                        Batch atomic layer deposition

                        Pilot scale roll to roll sputtering

                        In-line and batch sputtering

                        In-line HiTUS sputtering coater (low ion energy bombardment during film growth)

                        Analysis, characterisation and metrology


CPI can offer:

                        Access to a wide variety of thin-film deposition systems
