  • Publication number: 20180047693
    Abstract: Embodiments describe high aspect ratio and fine pitch interconnects for a semiconductor package, such as a package-on-package structure. In an embodiment, the interconnects are formed with a no-slump solder paste. In an embodiment, the no-slump solder paste is printed in an uncured state, and is then cured with a liquid phase sintering process. After being cured, the no-slump solder paste will not reflow at typical processing temperatures, such as those below approximately 400° C. According to embodiments, the no-slump solder paste includes Cu particles or spheres, a solder matrix component, a polymeric delivery vehicle, and a solvent. In an embodiment, the liquid phase sintering produces a shell of intermetallic compounds around the Cu spheres. In an embodiment, the sintering process builds a conductive metallic network through the no-slump solder paste.

  • Publication number: 20170200621
    Abstract: Embodiments describe a semiconductor package that includes a substrate, a die bonded to the substrate, and a solder paste overmold layer formed over a top surface of the die. In an embodiment, the solder paste comprises a high-melting point metal, a solder matrix, intermetallic compounds and a polymer. The overmold layer has a high elastic modulus, a coefficient of thermal expansion similar to the substrate, and reduces the warpage of the package. In an embodiment, interconnects of a semiconductor package are formed with a no-slump solder paste that includes vents. Vents may be formed through a conductive network formed by the high-melting point metal, solder matrix and intermetallic compounds. In an embodiment, vents provide a path through the interconnect that allows for moisture outgassing. In an embodiment, a mold layer may be mechanically anchored to the interconnects by the vents, thereby providing improved mechanical continuity to the mold layer.
