  • Publication number: 20240203901
    Abstract: A semiconductor device includes a wiring board having a first surface and a ground electrode exposed to the first surface, a stacked body provided above the first surface and having a chip structure body and a first resin layer that seals the chip structure body, a second resin layer that seals the stacked body, a third resin layer provided between the wiring board and the stacked body, and a first conductive shield layer provided between the first resin layer and the first surface and between the first resin layer and the second resin layer, and being in contact with the ground electrode. The first conductive shield layer is in contact with the side surface of the first resin layer. When looking the ground electrode from a direction perpendicular to the first surface, the ground electrode is provided outside of the first resin layer.

  • Patent number: 11749667
    Abstract: A semiconductor manufacturing method of mounting a semiconductor chip or a stacked body of semiconductor chips on a support substrate placed on a stage, determines whether a predetermined condition is satisfied during a mounting processing of the semiconductor chip or the stacked body, evacuates, together with the support substrate, the semiconductor chip or the stacked body that has mounted on the support substrate before the determination when it is determined that the predetermined condition is satisfied, determines whether to resume the mounting processing of the semiconductor chip or the stacked body after the evacuation; and returns the evacuated semiconductor chip or the evacuated stacked body to a position before the evacuation and continuing the mounting processing when it is determined that the mounting processing is resumed.

  • Patent number: 11024619
    Abstract: A semiconductor manufacturing apparatus that sequentially stacks a plurality of semiconductor chips while aligning the plurality of semiconductor chips on a stage. A condition determinator determines whether an apparatus performing a mounting processing stops during a mounting processing of the plurality of semiconductor chips. An evacuation controller evacuates, when it is determined that the apparatus performing the mounting processing stops, a group of semiconductor chips that has been stacked before the determination. A resuming determinator determines whether to resume the mounting processing after it is determined that the predetermined condition is satisfied. A return controller returns the evacuated group of semiconductor chips to a position before the evacuation and continues the mounting processing when it is determined that the mounting processing is resumed.
