An apparatus and method for transmittingreceiving a Channel State Information-Reference Symbol in a relay network system are provided. The invention provides the ability to create multiple ion flow channels and then form new chemical compositions therefrom. In another aspect of the invention, cantilevered support beams are made from a thicker material than the switching pad. The P-type fiber and N-type fiber in one pair of transmission lines are preferably colored differently than the P-type fiber and N-type fiber in other pairs. The ashing processing period of time in the first ashing processing step is shorter than the ashing processing period of time in the second ashing processing step.
