A copper bonding pad is directly supported by a copper via pad structure, the copper via pad structure having substantially the same geometry and dimensions as the copper bonding pad. The unwound web is delivered to a processing station while being maintained in tension. Systems of the present invention further include a light source that can be directed through the aforementioned means or another opening to the binder-printed surface to test for diffraction. An a-Si channel layer is formed above the gate electrode. An exact shift operation conformed to the vehicle weight and the running load can be performed, and an enhanced fuel consumption can be attained.
