A shippingstorage rack comprising an upward biasing arrangement has been achieved. The device may include a plurality of semiconductor devices and a controller to control the plurality of semiconductor devices. The adhesive material is supplied to the depressed portion so that it is retained therein. Next, a set of differences between the post-OPC layout and the circuit layout are calculated and a dataset containing these differences are generated In some embodiments the dataset is generated during the OPC process. If the request is validated, a switchover command unit directs a telephone exchange to change its setup.
