摘要:
Dendrimer/hyperbranched materials are combined with polyimide to form a low CTE material for use as a dielectric substrate layer or an underfill. In the alternative, ruthenium carbene complexes are used to catalyze ROMP cross-linking reactions in polyimides to produce a class of cross-linkable, thermal and mechanical stable material for use as a dielectric substrate or underfill. In another alternative, dendrimers/hyperbranched materials are synthesized by different methods to produce low viscosity, high Tg, fast curing, mechanically and chemically stable materials for imprinting applications.
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.

A chip-packaging composition includes a polymer of a bis-maleimide. A process includes formation of the chip-packaging composition including adding particulate fillers to achieve a coefficient of thermal expansion of about 20 ppm/K. A method includes assembly of the chip-packaging composition with a die or a mounting substrate. A computing system is also included that uses the chip-packaging composition.

摘要:
Integrated circuit packages and their manufacture are described, wherein the packages comprise dendrimers or hyperbranched polymers. In some implementations, the dendrimers or hyperbranched polymers include repeat units having one or more ring structures and having surface groups to react with one or more components of a plastic. In some implementations, the dendrimers or hyperbranched polymers have a glass transition temperature of less than an operating temperature of the integrated circuit and form at least a partially separate phase.
摘要:
In relation to a nut and bolt combination that can fasten together a myriad of objects, one constant has remained the same; the nut must be threaded on to or off of the bolt to facilitate the proper employment of the two complementary devices. Oftentimes this can be a tedious, time consuming exercise. In this invention, a nut, unique bolt and unique washer combination work as one unit to facilitate the speedy removal and reinstatement, respectively, of said nut, bolt and washer from and to any two or more objects meant to be joined together by use of such a device.
摘要:
An embodiment is a cyclic olefin semiconductor package. Further an embodiment is a combination of a cyclic olefin monomer and a ruthenium-based catalyst that is stable at approximately room temperature and humidity for extended storage life and pot life, and that can be screen printed or valve/jet deposited.

摘要:
Smart curing by coupling a catalyst to one or more surface(s) of one or more microelectronic element(s) is generally described. In this regard, according to one example embodiment, a catalyst is coupled to one or more surface(s) of one or more microelectronic element(s) to promote polymerization of an adhesive brought in contact with the catalyst.
