A method of manufacturing a structure that includes a substrate provided with a through hole, and a resin layer provided on a front surface of the substrate to close the through hole, includes, in order, preparing the substrate including the through hole and including a support substrate on a back surface of the substrate to close the through hole, bonding a dry film to a front surface of the substrate, the dry film including a support member and a resin layer on the support member, to close the through hole with the resin layer and turn the through hole into a closed space with the substrate, the support substrate, and the dry film, opening the through hole turned into the closed space from the support substrate side, and separating the support member from the dry film while retaining the resin layer on the front surface of the substrate.
Fan-out electronic device
An electronic device (100) includes a substrate (110) and an integrated circuit (120) provided on the substrate (110) having a surface facing away from the substrate (110). An insulating layer (150) extends over the substrate (110) and around the integrated circuit (120) to define an interface (154) between the insulating layer (150) and the integrated circuit (120). An electrically conductive via (130) is provided on the surface of the integrated circuit (120). An insulating material (140) extends over the via (130) and includes an opening (142) exposing a portion of the via (130). A repassivation member (162) extends over the insulating layer (150) and has a surface (164) aligned with the interface (154). An electrically conductive redistribution member (181) is electrically connected to the via (130) and extends over the repassivation member (162) into contact with the insulating layer (150).
Method for via formation by micro-imprinting
A method and apparatus for forming a plurality of vias in panels for advanced packaging applications is disclosed, according to one embodiment. A redistribution layer is deposited on a substrate layer. The redistribution layer may be deposited using a spin coating process, a spray coating process, a drop coating process, or lamination. The redistribution layer is then micro-imprinted using a stamp inside a chamber. The redistribution layer and the stamp are then baked inside the chamber. The stamp is removed from the redistribution layer to form a plurality of vias in the redistribution layer. Excess residue built-up on the redistribution layer may be removed using a descumming process. A residual thickness layer disposed between the bottom of each of the plurality of vias and the top of the substrate layer may have thickness of less than about 1 μm.
