Due to their high-power density and long lifetime, microsupercapacitors have been considered as an efficient energy supply/storage solution for the operation of small electronic devices. However, their fabrication remains confined to 2D thin-film microdevices with limited areal energy. In this study, the integration of all-solid-state 3D interdigitated microsupercapacitors on 4 in. silicon wafers with record energy density is demonstrated. The device electrodes are composed of a pseudocapacitive hydrated ruthenium dioxide RuO deposited onto highly porous current collectors. The encapsulated devices exhibit cell capacitance of 812 mF cm per footprint area at an energy density of 329 mJ cm , which is the highest value ever reported for planar configuration. These components achieve one of the highest surface energy/power density trade-offs and address the issue of electrical energy storage of modern electronics.
