Denton Vacuum Acquires Isoflux Inc. Cylindrical Cathode Portfolio

June 09, 2020

Moorestown, NJ, June 9, 2020 — Denton Vacuum LLC today announced it has purchased the assets of Isoflux Inc. relating to their cylindrical cathode technology. This includes both equipment intellectual property and patents on the cylindrical cathode, and process patents for its application to several biomedical applications.

Frank Cumbo, President and CEO of Denton Vacuum, comments that “we see tremendous opportunity to expand our IP portfolio, augmenting our existing product line, and being better able to address both new and existing applications and markets. We see demand for extremely uniform, dense films on a wide variety of highly curved surfaces like medical implants, and this will augment the technology capability of our Discovery sputtering platform. By integrating the Isoflux cylindrical cathode onto our Discovery 200 module, we are able to provide a highly reliable, turnkey coating solution for these applications.”

Dr. David Douglass, Senior Product Manager at Denton Vacuum, added that, in addition to medical devices, “we are particularly interested in the ability to apply highly uniform metal and dielectric films to curved optics, without the use of masks or shapers. This can greatly improve cost of ownership and yield, potentially opening up new applications requiring optical filters on curved substrates. By utilizing the flexible, semiconductor-grade Discovery platform, we are able to provide a reliable, high uptime system for these unique applications.”
