A tool handling system for transporting a sealing tool is provided. In some embodiments, an N-channel transistor, which can be ESD damaged, is selectively turned on and made conducting. Each diode is addressable as part of an array, corresponds to a physical location of the chip, and is connected in series to a stack. The semiconductor substrate is removed from the process chamber. In the idle mode, the system displays programmed non-advertisement information. The polymer can be a photoresist.
