Abstract (en)

[origin: WO2019177742A1] A method of electronic device package fabrication includes dispensing a planarizing liquid into a region between adjacent features that protrude from a substrate. The planarizing liquid is then processed to provide a hardened, substantially solid material in the region between adjacent features. In some examples, the planarizing liquid can be a dielectric material used in the formation of multilevel redistribution layers or a packaging resin material used for packaging semiconductor chips. A planarization apparatus of an example includes a substrate support, a liquid dispensing system configured to dispense the planarizing liquid onto the substrate, a hardening system for hardening the planarizing liquid, and a planar element system to press into the planarizing liquid.
