Dynamic Reverse Pulsing – What About the Anode?
十二月 04, 2023
By Gayatri Rane
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
十月 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.

Success is in the Details: Not-So-Obvious Subtleties of Voltage Control
四月 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).
