Abstract: A semiconductor package includes: a package substrate; an interposer disposed on the package substrate; a first semiconductor chip mounted on the interposer; a second semiconductor chip mounted on the interposer adjacent to the first semiconductor chip, the second semiconductor chip having an overhang portion that does not overlap the interposer in a vertical direction; a first underfill disposed between the package substrate and the interposer, the first underfill having a first extension portion extending from a side surface of the interposer; a second underfill disposed between the interposer and the second semiconductor chip, the second underfill having a second extension portion extending to an upper surface of the package substrate along at least a portion of the first extension portion of the first underfill, wherein the second extension portion protrudes from the overhang portion contact the upper surface of the package substrate.

Abstract: A semiconductor package is provided to include a package substrate, a plurality of semiconductor chips mounted on the package substrate, an interposer arranged between the package substrate and the plurality of semiconductor chips, a plurality of passive elements mounted on the package substrate and spaced apart from the interposer, a first stiffener positioned on the package substrate and including a first hole accommodating the interposer and a second hole accommodating the plurality of passive elements, and a second stiffener positioned on the first stiffener and including a third hole communicating with the first hole. The first stiffener has a first coefficient of thermal expansion, and the second stiffener has a second coefficient of thermal expansion different from the first coefficient of thermal expansion.
