A semiconductor device has first wiring layers 30 and a plurality of dummy wiring layers 32 that are provided on the same level as the first wiring layers 30. The screw cap is locked to the screw threads of a vial, when the vial is empty, with one of two latches that are integral to the cap assembly and can lock the cap to the vial. The SIP address translator extracts addresses for translation, and makes a query to the address translator. The nut is pivotably and slidably mounted between the arms with the pins received in the elongated holes formed in the arms. In one implementation, the energy source monitoring system detects when voltages in the energy source have fallen below a cutoff level, yet allows the device to continue running until the operator finishes the current device operation.
