Three dimensional (3D) IC has been proposed for high performance and low power in recent years. Due to the narrow gap between stacked chips and fine pitch of bumps, new inter chip fill (ICF) which can be used for pre-applied ICF process is required. The heat generation of 3D-IC is higher than 2D, so that a high thermal conductive inter chip fill (HT-ICF) is simultaneously required to dissipate the heat from 3D-IC and for the purpose of pre-applied ICF and HT-ICF, highly active flux agent and thermal conductive materials such as filler and matrix have been called for at the same time. In this study, some kind of materials were prepared, synthesized and optimized for the HT-ICF, and we evaluated its characteristic and confirmed applicability to pre-applied joining for 3D-IC.

Abstract Controllable synthesis of highly active micro/nanostructured metal electrocatalysts for oxygen evolution reaction (OER) is a particularly significant and challenging target. Herein, we report a 3D porous sponge-like Ni material, prepared by a facile hydrothermal method and consisting of cross-linked micro/nanofibers, as an integrated binder-free OER electrocatalyst. To further enhance the electrocatalytic performance, an N-doping strategy is applied to obtain N-doped sponge Ni (N-SN) for the first time, via NH3 annealing. Due to the combination of the unique conductive sponge structure and N doping, the as-obtained N-SN material shows improved conductivity and a higher number of active sites, resulting in enhanced OER performance and excellent stability. Remarkably, N-SN exhibits a low overpotential of 365 mV at 100 mA cm−2 and an extremely small Tafel slope of 33 mV dec−1, as well as superior long-term stability, outperforming unmodified sponge Ni. Importantly, the combination of X-ray photoelectron spectroscopy and near-edge X-ray adsorption fine structure analyses shows that γ-NiOOH is the surface-active phase for OER. Therefore, the combination of conductive sponge structure and N-doping modification opens a new avenue for fabricating new types of high-performance electrodes with application in electrochemical energy conversion devices.
