A radio frequency identification system and method for tracking and locating an RFID tag is disclosed. A first slider is formed by connecting center rails, on an outside of inner rails to each other by brackets, and a second slider, having a seat, is formed by connecting outer rails to each other by a bracket. A parasitic substrate resistor is formed in parallel electrical connection with the sense resistor between the source regions of the HVFET and the sense FET. The nanotubes are pretreated to reduce the level of metallic and particulate impurities to a preselected level, and the preselected metal and particulate impurities levels are selected to be compatible with an electronics manufacturing process.
