摘要:
An underfill composition is formulated to increase the surface tension thereof for use in capillary underfilling of an integrated circuit die that is coupled to a mounting substrate. A method includes mixing a surface tension-increasing additive with a bulk polymer and a hardener and allowing the underfill composition to flow between the integrated circuit die and the mounting substrate. An article is achieved by the method. The article can be assembled into a computing system.

摘要:
A stress-relief layer is formed by dispensing a polymer upon a substrate lower surface under conditions to partially embed a low melting-point solder bump that is disposed upon the lower surface. The stress-relief layer flows against the low melting-point solder bump. A stress-compensation collar is formed on a board to which the substrate is mated, and the stress-compensation collar partially embeds the low melting-point solder bump. An article that exhibits a stress-relief layer and a stress-compensation collar is also included. A computing system that includes the low melting-point solder, the stress-relief layer, and the stress-compensation collar is also included.

摘要:
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.

摘要:
A mounting substrate includes an at least double-embossed structure on one side for containing metallization traces. The mounting substrate is overlaid with an uncured polymer and it is imprinted and cured by infrared or microwave energy. A second uncured polymer is placed over the cured polymer first film. It is imprinted and also cured under conditions that allow retention of significant features of the cured polymer first film. A chip package is also made of the double-embossed structure. The chip package can include a heat sink. A computing system is also disclosed that includes the double-embossed structure.
