Pre-Treatment

Our pre-treatment sources are used for adhesion promotion of films deposited on metallic, glass, ceramic and polymer substrates, they are utilized before the deposition zones to treat the substrate surface. Improved adhesion of films deposited in R2R web coating systems is achieved by removing contamination from surfaces and splitting chemical bonds on polymer substrates prior to thin film coating. The use of pre-treatment improves the final performance of sputter deposited films and thermal evaporation deposited films. With our in-house manufacturing capabilities we can design and integrate pre-treatment sources for PVD coating equipment. INTELLIVATION can match the plasma treater technology to meet your thin film requirements.

Glow Discharge

INTELLIVATION offers water cooled DC or AC driven glow discharge sources. The use of a glow discharge improves the performance of sputter and thermal evaporation deposited films.

A plasma is ignited between two tubes by biasing them either with AC, alternating their polarity or biasing them with a DC power supply. A treatment gas is introduced to the plasma and the activated treatment gas interacts with the substrate to affect a chemical change that increases the surface energy of the substrate to improve adhesion.

Anode Layer Source

Our web coating anode layer source provides an ion beam used for adhesion promotion of PVD coatings on metallic, glass, ceramic and some polymer substrates. The anode layer source provides higher energy to the ions impacting the substrate, ion energy than glow discharge sources. Anode layer sources are utilized for more challenging substrates to promote adhesion.

A plasma is magnetically confined between a slit that acts as a cathode. The plasma confined in the slit creates a beam of positive ions that are repelled by the positive bias of and anode. The energy of the repelled positive ions is controlled by the bias put on the slits by the power supply and the pressure.
