Disclosed is a method for manufacturing an electronic component device, including: preparing a sealing structure having a sealing layer having two opposing main surfaces, an electronic component, and a connection portion, the connection portion being exposed on a circuit surface that is one main surface of the sealing layer; preparing a rewiring structure having a rewiring portion having two opposing main surfaces, and a plurality of bumps; and bonding the sealing structure and the rewiring structure in a direction that the circuit surface and the plurality of bumps face each other, with an insulating layer intervening.

Method for manufacturing electronic component device and electronic component device

Disclosed is a method for manufacturing an electronic component including: forming a via hole extending in a thickness direction of a curable sealing resin layer provided on a base material by an imprint method of pressing a mold into the sealing resin layer from a side opposite to the base material; curing the sealing resin layer; filling the via hole with a conductor precursor; and forming a conductive via by heating the conductor precursor filled in the via hole.

Disclosed is a method for manufacturing an electronic component device, including: preparing a sealing structure including a sealing layer having two opposing main surfaces, an electronic component, and a connection portion, the connection portion being exposed on a circuit surface that is one main surface of the sealing layer; preparing a rewiring structure including a rewiring portion having two opposing main surfaces, and a plurality of bumps; and bonding the sealing structure and the rewiring structure in a direction that the circuit surface and the plurality of bumps face each other, with an insulating adhesive layer intervening, and thereby connecting the sealing structure and the rewiring structure.

Method for manufacturing electronic component device, and electronic component device

Disclosed is a method for producing an electronic component, the method including: disposing a plurality of electronic components on an adhesive layer of a composite substrate including a support, a temporary fixing material layer, and the adhesive layer with a connection part in contact with the adhesive layer interposed between the adhesive layer and the electronic components; fixing the plurality of electronic components to the composite substrate by curing the adhesive layer; forming a sealing layer sealing the electronic components; obtaining a sealed structure by peeling off the temporary fixing material layer from the adhesive layer; and a forming a circuit surface by grinding the sealed structure from the adhesive layer side. The plurality of electronic components include an IC chip and a chip-type passive component. The passive component is disposed on the adhesive layer by a method including in the following order: disposing a conductor precursor for pattern formation as the connection part on the adhesive layer; placing the passive component on the conductor precursor; and forming a conductive pattern as the connection part by heating the conductor precursor.
