  • Patent number: 9391043
    Abstract: A semiconductor device including a relatively thin interposer excluding a through silicon hole and a manufacturing method thereof are provided. The method includes forming an interposer on a dummy substrate. The forming of the interposer includes, forming a dielectric layer on the dummy substrate, forming a pattern and a via on the dielectric layer, and forming a seed layer at the pattern and the via of the dielectric layer and forming a redistribution layer and a conductive via on the seed layer. A semiconductor die is connected with the conductive via facing an upper portion of the interposer, and the semiconductor die is encapsulated with an encapsulant. The dummy substrate is removed from the interposer. A bump is connected with the conductive via facing a lower portion of the interposer.
    Type: Grant

  • Publication number: 20100242275
    Abstract: In a method of manufacturing an inspection apparatus for inspecting an electronic device, a sacrificial substrate is formed into a substrate pattern including a through-hole. A principal substrate including an internal wiring penetrating from a first surface to a second surface thereof is combined with the substrate pattern in such a configuration that the through-hole is positioned over the internal wiring, thereby forming a combined structure. A filling structure is formed in the through-hole of the substrate pattern, and the filling structure is electrically connected to the internal wiring of the principal substrate. The substrate pattern is removed from the combined structure, and thus the filling structure is formed into a probe structure on the principal substrate. The probe structure may be connected to the principal substrate without any adhesives such as a solder, to thereby prevent electrical resistance increase and excessive thermal stress.
