Abstract:
An electronic component incorporated substrate includes a first substrate and a second substrate electrically connected to each other by a spacer unit. An electronic component is mounted on the first substrate and arranged between the first substrate and the second substrate. A first encapsulating resin is formed between the first substrate and the second substrate to encapsulate the electronic component. A second encapsulating resin is formed on a first surface of the first encapsulating resin to fill a space between the first encapsulating resin and the second substrate. The spacer unit includes a stacked structure of a first solder ball, a metal post, and a second solder ball stacked in a stacking direction of the first substrate and the second substrate.
Abstract:
An electronic part embedded substrate is disclosed. The electronic part embedded substrate includes a first substrate, a second substrate, an electronic part, an electrically connecting member, and a sealing member. A method of producing an electronic part embedded substrate is also disclosed. The method includes mounting an electronic part onto a first substrate, laminating a second substrate on the first substrate through an electrically connecting member; and filling a space between the first substrate and the second substrate with a sealing member to seal the electronic part.

Abstract:
A wiring substrate includes first and second wiring structures. The first wiring structure includes a core substrate, first and second insulation layers each formed from a thermosetting insulative resin including a reinforcement material, and a via wire formed in the first insulation layer. The second wiring structure includes a wiring layer formed on upper surfaces of the first insulation layer and the via wire, an insulation layer formed on the upper surface of the first insulation layer, and an uppermost wiring layer including a pad used to electrically connect a semiconductor chip and the wiring layer. An outermost insulation layer stacked on a lower surface of the second insulation layer exposes a portion of a lowermost wiring layer stacked on the lower surface of the second insulation layer as an external connection pad. The second wiring structure has a higher wiring density than the first wiring structure.
