  • Patent number: 9484277
    Abstract: Highly reliable interconnections for microelectronic packaging. In one embodiment, dielectric layers in a build-up interconnect have a gradation in glass transition temperature; and the later applied dielectric layers are laminated at temperatures lower than the glass transition temperatures of the earlier applied dielectric layers. In one embodiment, the glass transition temperatures of earlier applied dielectric films in a build-up interconnect are increased through a thermosetting process to exceed the temperature for laminating the later applied dielectric films. In one embodiment, a polyimide material is formed with embedded catalysts to promote cross-linking after a film of the polyimide material is laminated (e.g., through photo-chemical or thermal degradation of the encapsulant of the catalysts).
