Method of manufacturing a component built-in module
First Claim
1. A method for manufacturing a component built-in module, comprising the steps of:
- forming a first inner via in an electric insulation layer;
mounting an electronic component on a first wiring pattern; and
laminating the electric insulation layer and another wiring pattern different from said first wiring pattern in this order on a surface of the first wiring pattern on which the electronic component is mounted so theat said first wiring pattern and the another wiring pattern, which are provided opposite each other with the electric insulation layer being interposed therebetween, are electrically connected through the first inner via, wherein the electric insulation layer before being laminated has a thickness smaller than a height of the electronic component in a direction of the lamination.

Abstract
A component built-in module includes an electric insulation layer, first wiring patterns in a plurality of layers that are laminated with the electric insulation layer being interposed therebetween, at least one first inner via electrically connecting the first wiring patterns in different layers with each other, and at least one electronic component that is embedded in the electric insulation layer and is mounted on any one of the first wiring patterns in the plurality of layers, wherein at least one of the first inner vias is present in a range that overlaps a range in which the electronic component is present in a lamination direction in which the first wiring patterns are laminated, and has a height in the lamination direction that is smaller than a height of the electronic component. Since the first inner via has a small height, the via diameter can be decreased. Therefore, it is possible to provide a component built-in module that has high reliability and is suitable for high-density component mounting.

11. A method for manufacturing a component built-in module, comprising the steps of:
-
forming a first inner via in an electric insulation layer;
preparing a wiring board including second wiring patterns in at least two layers, and a through hole and/or a second inner via that electrically connects the second wiring patterns in different layers with each other;
mounting an electronic component on the second wiring pattern that is exposed on a surface of the wiring board; and
laminating the electric insulation layer and a first wiring pattern in this order on the second wiring pattern on which the electronic component is mounted so that the second wiring pattern and the first wiring pattern, which are provided opposite each other with the electric insulation layer being interposed therebetween, are electrically connected through the first inner via, wherein the electric insulation layer before being laminated has a thickness smaller than a height of the electronic component in a direction of the lamination. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
