Abstract:Simplifying the bonding technique used to package power devices is crucial for electric vehicles and 5G communication. Herein, a transparent liquid Ag-based complex was employed to simplify the Ag sintering process. The complex can directly fabricate Ag nanostructures on substrates and dies by thermal decomposition at 180 °C for 30 min. These nanostructures consisted of linked nanoparticles with a wide size distribution and exhibited remarkable compressibility, indicating an excellent potential for sintering. … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
