摘要: A wiring board has an insulating layer, a plurality of wiring layers formed in such a way as to be insulated from each other by the insulating layer, and a plurality of vias formed in the insulating layer to connect the wiring layers. Of the wiring layers, a surface wiring layer formed in one surface of the insulating layer include a first metal film exposed from the one surface and a second metal film embedded in the insulating layer and stacked on the first metal film. Edges of the first metal film project from edges of the second metal film in the direction in which the second metal film spreads. By designing the shape of the wiring layers embedded in the insulating layer in this manner, it is possible to obtain a highly reliable wiring board that can be effectively prevented from side etching in the manufacturing process and can adapt to miniaturization and highly dense packaging of wires.

摘要: A transparent board is positioned on a support board provided with a positioning mark, and a release material is provided. A semiconductor element is then positioned so that the electrode element faces upward, and the support board is then removed. An insulating resin is then formed on the release material so as to cover the semiconductor element; and a via, a wiring layer, an insulation layer, an external terminal, and a solder resist are then formed. The transparent board is then peeled from the semiconductor device through the use of the release material. A chip can thereby be mounted with high precision, there is no need to provide a positioning mark during mounting of the chip on the substrate in the manufacturing process, and the substrate can easily be removed. As a result, a semiconductor device having high density and a thin profile can be manufactured at low cost.
