Abstract

The present invention provides a solid electrolyte switching device, which can maintain an on or off state when the power source is removed, the resistance of which in on the state is low, and which is capable of integration and re-programming, and FPGA and a memory device using the same, and a method of manufacturing the same.A solid electrolyte switching device (10, 10′, 20, 20′) comprises a substrate (11) in which surface is coated with an insulation layer, a first interconnection layer (13) set on said substrate (11), an ion supplying layer (17) set on said first interconnection layer (13), a solid electrolyte layer (16) set on said ion supplying layer (17), an interlevel insulating layer (12) having a via hole set to cover said first interconnection layer (13), said ion supplying layer (17), and said solid electrolyte layer (16), a counter electrode layer (15) set to contact said solid electrolyte layer (16) through the via hole of said interlevel insulating layer (12), and a second interconnection layer (14) set to cover said counter electrode layer (15). The switching device can be provided in which the on state, or the off state can be arbitrarily set by the threshold volta…
