The invention relates to a method and a system for routing electric circuits in integrated circuit chip design. The system includes an axial conducting loop formed by the drill string for conducting an axial electrical signal embodying the information between a first axial position and a second axial position in the drill string, which axial conducting loop extends between the first and second axial positions. In certain of the gap cells, multiplexers are provided to transfer signals from IO lines to data lines. A set of experts, included in the list of experts, that are available for instant messaging communication, is identified. Finally, at least one protective thermal layer is applied over the oxidized aluminum layer.
