High‐Rate Deposition and Characterization Study of CoZrO Films for On‐Chip Power Applications

open access: yesAdvanced Engineering Materials, EarlyView.
This study introduces a high‐rate reactive sputtering process for CoZrO films, aimed at large‐scale production of on‐chip magnetic components compatible with complementary metal oxide semiconductor (CMOS) fabrication. Characterization of the deposited films reveals that ideal magnetic properties require chemical compositions in a narrow Co:O range and ...

An Examination of Aerosol Jet‐Printed Surface Roughness and its Impact on the Performance of High‐Frequency Electronics

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores aerosol jet‐printed (AJP) surface roughness, its effects on the performance of microwave electronics, and its process contributors. First, an electromagnetic model is vetted for AJP's unique roughness signature. Simulations are built which show process‐induced roughness is as significant as conductor resistivity in driving microwave

Enhancing the Age‐Hardening Response of Laser Powder‐Bed Fusion WE43 Alloy through Microstructural Control

open access: yesAdvanced Engineering Materials, EarlyView.
Laser powder‐bed fusion (L‐PBF) can produce dense WE43 magnesium alloy parts, but their mechanical properties are limited by a nonhomogeneous microstructure. This study investigates the effects of varying direct aging (T5) and artificial age‐hardening (T6) conditions on microstructure and strength. Optimized T6 treatment significantly improves strength
