Method of manufacturing layered chip package
A layered chip package includes a main body, and wiring disposed on at least one side surface of the main body. The main body includes a plurality of layer portions stacked. In a method of manufacturing the layered chip package, a plurality of structures are initially formed. Each structure includes at least one main-body-forming portion that is to be the main body and that has a pre-wiring surface. Next, the plurality of structures are surrounded with a jig and thereby aligned so that their pre-wiring surfaces face upward. The jig has a top surface that is lower in level than the pre-wiring surfaces. Next, a resin layer covering the jig and the structures is formed using a resin film. Next, the resin layer is polished until the pre-wiring surfaces are exposed. Next, the wiring is formed on the pre-wiring surfaces simultaneously. Next, the main-body-forming portions are separated from each other.
