SWITCHING DEVICE AND ELECTRONIC CIRCUIT APPARATUS HAVING THE SAME

摘要

PURPOSE: A switching device and an electronic circuit apparatus having the same are provided to be capable of improving the reliability of the device and enhancing speed characteristics. CONSTITUTION: A switching device is provided with an insulation substrate, the first region(110) formed on one side of the insulation substrate, and the second region(120) formed on the other side of the insulation substrate. At this time, the first and second region are spaced apart from each other. The first and second region are shrunk and expanded according to the intensity of laser beam. Preferably, the first and second region are made of chalcogenide. Preferably, the first and second region are made of Ge-Sb-Te material. Preferably, the first and second region are capable of being connected with each other in an expansion state.
