Abstract
The present invention provides a multi-layer selector device exhibiting a low leakage current by controlling a threshold voltage. According to an embodiment of the present invention, the multi-layer selector device comprises: a substrate; a lower electrode layer disposed on the substrate; an insulating layer disposed on the lower electrode layer and having a via hole passing through to expose the lower electrode layer; a switching layer disposed on the lower electrode layer in the via hole, performing a switching operation by forming and destroying a conductive filament, and made of a multi-layer to control the formation of the conductive filament; and an upper electrode layer disposed on the switching layer.
