Dynamic Reverse Pulsing – What About the Anode?
December 04, 2023
A previous AE blog, Dynamic Reverse Pulsing – What About Duty Cycle?, discussed reactive sputter deposition of insulating thin films in large-area coaters, describing the benefits of using the Dynamic Reverse Pulse (DRP) power-delivery mode over the bipolar (BP) mode of dual magnetron sputtering. In DRP mode , dual targets are bipolar pulsed against an explicit anode and the duty cycle can be varied so that the polarity is positive on the target for a shorter time during pulsing. This allows clearing of charge build-up on the targets. In our studies, DRP mode showed increased deposition rate and reduced substrate temperature when compared to similar depositions with the BP mode.

CT Imaging: Navigating the Complex Power Needs of Current and Next Generation CT Systems
October 09, 2023
Computed Tomography (CT) is a computerized imaging technique used in radiology. A rapidly rotating X-ray beam and detector are used to generate cross-sectional images – so-called slices – that form the volumetric and very detailed internal image of the body.

Dual Magnetron Sputtering: Delivering High Power*
June 17, 2015
Current source supplies are ideal for pulsed dual magnetron sputtering (DMS). They have the advantage of little to no current rise when an arc occurs, and they enable arc detection by voltage fall due to high incremental impedance.

Success is in the Details: Not-So-Obvious Subtleties of Voltage Control
April 08, 2014
The possibility of controlling reactive sputtering processes in the transition region has been intriguing and compelling for as long as I have been in the thin-films industry (actually, since before I joined the industry in 1995).
