Abstract:
1. A semiconductor device fabrication method comprising: temporarily fixing, on a base member formation member made of a material containing at least a semi-hardened thermosetting resin, a plurality of semiconductor constructing bodies each having a semiconductor substrate and a plurality of external connecting electrodes formed on the semiconductor substrate, such that the plurality of semiconductor constructing bodies are separated from each other; providing an insulating layer formation sheet, which contains at least a semi-hardened thermosetting resin, on the base member formation member around the semiconductor constructing bodies; heating and pressing to: (i) form a base member by hardening the thermosetting resin contained in the base member formation member, fixing the semiconductor constructing bodies to the base member by (ii) fix force of the thermosetting resin in the base member that is present on a surface of the base member contacting the semiconductor constructing bodies, and (iii) form an insulating layer on the base member around the semiconductor constructing bodies by hardening the insulating lever formation sheet; forming at least one layer of an interconnection on the semiconductor constructing bodies and insulating layer, such that the layer of the interconnection includes at least one interconnection connected to the external connecting electrodes; and cutting the insulating layer and base member between the semiconductor constructing bodies to obtain a plurality of semiconductor devices each including at least one of the semiconductor constructing bodies.
