    Abstract: Novel tools and techniques are provided for implementing a semiconductor package or a chip package, and more particularly methods, systems, and apparatuses (100) are provided for implementing a semiconductor package or a chip package including a stiffener member (130) with a via (135). In various embodiments, an apparatus (100) includes a substrate (105) and a connector (110) electrically coupled to the substrate (105). A stiffener member (130) is disposed between the substrate (105) and the connector (110) and configured to restrain at least one of the substrate (105) or the connector (110). A via (135) extends through a body of the stiffener member (130) and electrically couples the connector (110) to the substrate (105).

    Abstract: There is provided a manufacturing method for an insulating resin circuit substrate, which is a manufacturing method for an insulating resin circuit substrate which includes an insulating resin layer composed of a polyimide resin and a circuit layer consisting of metal pieces disposed in a circuit pattern shape on one surface of the insulating resin layer. The manufacturing method includes a temporary fixing step of pressurizing the metal pieces toward the resin sheet material while heating the metal pieces to temporarily fix the metal pieces and a joining step of disposing a cushion material on a side of the metal pieces which are temporarily fixed and pressurizing the metal pieces and the resin sheet material in a laminating direction, while heating the metal pieces and the resin sheet material, to join the resin sheet material and the metal pieces. Regarding all the metal pieces, in a case where a ratio w/t of a minimum width w to a thickness t exceeds 0.5, a heating temperature in the temporary fixing step is 150°C or higher, and in a case where the metal pieces include a narrow-width metal piece having the ratio w/t of the minimum width w to the thickness t of 0.5 or less, the heating temperature in the temporary fixing step is 350°C or higher.
