Abstract

Dielectrics are the key materials for all IC circuits, electronic packages, and energy storage devices as well as flexible electronics.To develop new dielectrics with unique properties for different applications, 0-3 composites, especially polymer-based dielectric 0-3 composites, have been extensively studied in recent years.In this talk, some applications will be discussed first to promote the materials development. The recent developments in dielectric 0-3 composites including materials and fabrication processes are presented along with the challenges for further developments. Finally, the physics behind the properties of dielectric composites is presented. The shortcomings of current understandings are discussed along new experimental results.
