Patent ID: 7504317

Claim:
A manufacturing method of a semiconductor device comprising: forming a plurality of first semiconductor integrated circuits, and a plurality of second semiconductor integrated circuits arranged to surround at least one of the plurality of first semiconductor integrated circuits, over a first substrate; adhering a second substrate to cover the plurality of first semiconductor integrated circuits and the plurality of second semiconductor integrated circuits; separating the first substrate and the second substrate from each other by applying an external force between the first substrate and the second substrate; transferring the plurality of first semiconductor integrated circuits to a third substrate; removing the second substrate; forming a protective layer to cover a top surface and a side surface of the plurality of first semiconductor integrated circuits and a surface of the third substrate in a periphery of the plurality of first semiconductor integrated circuits; and dividing the third substrate and the protective layer so that the plurality of first semiconductor integrated circuits is divided into individual pieces and part of the third substrate remains in the periphery of the plurality of first semiconductor integrated circuits.
