Abstract

A process of packaging a microelectronic chip includes wafer-level application of a chip-packaging composition that includes a polymer of a bis-maleimide. A process includes wafer-level addition of the chip-packaging compositions that include adding particulate fillers to achieve a coefficient of thermal expansion of about 20 ppm/K. A computing system is also included that uses a microelectronic die that was processed with the bis-maleimide at the wafer level, before singulation.
