Abstract:
1. A manufacturing method of a semiconductor device, comprising: preparing a plurality of objects to be processed each including a wiring board, a semiconductor chip mounted on the wiring board, and a sealing resin layer sealing the semiconductor chip; preparing a tray including a plurality of housing parts, and depressed portions provided in the plurality of the housing parts respectively and having non-penetrating shapes; disposing, in each of the plurality of housing parts of the tray, the object so that an upper surface and side surfaces of the sealing resin layer and at least a part of side surfaces of the wiring board when a surface of the wiring board on which the semiconductor chip is mounted is defined as an upper side are exposed; disposing the tray in which the objects are housed on a table of a sputtering apparatus; and forming a conductive shield layer which covers the upper surface and the side surfaces of the sealing resin layer and the at least a part of the side surfaces of the wiring board by sputtering a metal material on the object housed in each of the housing parts of the tray in the sputtering apparatus.
