There is provided a device and method for retransmitting error-detected data in a mobile communication system. The tool includes a shaft and a pair of arms coupled to the shaft. The switch has an actuator connected to the line. Alternately or additionally, in some embodiments, the native objects are further configured to proxy functionality between the layout engine and the scripting engine. Applications include microelectronics and microtechnology, in any manufacturing process that involves the degradation of a sacrificial material by diffusion of a chemical agent through a film that is permeable to this agent, for the production of air gaps, in particular the manufacture of air-gap interconnects for integrated circuits.
