The on/off state can be arbitrarily set by a threshold voltage applied between the ion supply layer (17) and the counter electrode layer (15). Thus a nonvolatile, low on-resistance switching device is provided.

An apparatus is provided for evaluating electrical characteristics by bringing a plurality of metal probes in contact with a minute area with low contact resistance. Metal probes (8) are formed on the free end of a cantilever (6) on which are formed a resistor (5), two electrodes (1, 2) for resistance detection, and an electrode (7) for measuring electrical characteristics. The tips of the metal probes (8) can project beyond the free end of the cantilever (6) to reach an area of about 10 nm size. The probe position is controlled by an atomic force microscope technique to achieve low contact resistance.

摘要:
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 voltage applied between the ion supplying layer (17) and the counter electrode layer (15), which is non-volatile, and the resistance of which in the on state is low. The switching device of the present invention is also simple and fine in structure, and hence makes it possible to provide smaller switching devices than are currently available. Further, using the switching device of the present invention as the switching device of an FPGA (30) makes it possible to provide re-programmable and fast operation FPGA (30). Using the switching device of the present invention as a memory cell of a memory device makes it possible to provide a non-volatile memory device with high programming and reading speed.
