A process for efficiently producing a poly-metal cluster composite, a patterning material obtainable by the process, and its patterning method are provided. A composite multi-layer surface-hardening coating is formed on at least the anterior surface of the resin substrate. Error correction circuitry coupled to the configuration data lines analyzes and corrects any errors in the configuration data that may occur due to a single event upset. Change in mobile registration is communicated via a suitable signaling link between a HLR and the chat group system. The tool applies the first set of design rules and the second set of design rules to the circuit layout to generate a revised circuit layout.
