PROBLEM TO BE SOLVED: To easily acquire identification information of a semiconductor device.SOLUTION: A semiconductor device PKG1 includes a plurality of lands LD formed on a mounting surface of a wiring board, in which a land LDc1 and a land LDc2 out of the plurality of lands LD are connected to fuse wiring Wfs. The fuse wiring Wfs is disconnected in the middle of a wiring channel and a fusing part NC1 and a fusing part NC2 which are formed on the disconnected part are opposite to each other and separated from each other. By doing this, identification information of 1 bit capable of being acquired by confirmation fo conduction between the land LDc1 and the land LDc2 is recorded in the fuse wiring Wfs.SELECTED DRAWING: Figure 8 |
