<p>A switching device (140 or 240) including a first dielectric layer (102 or 207) having a first top surface (108 or 218), two conductive features (104, 106 or 214, 216) embedded in the first dielectric layer (102 or 207), each conductive feature (104, 106 or 214, 216) having a second top surface (110, 112 or 220, 222) that is substantially coplanar with the first top surface (108 or 218) of the first dielectric layer (102 or 207), and a set of discrete islands of a low diffusion mobility metal (114a-c or 204a-c) between the two conductive features (104, 106 or 214, 216). The discrete islands of the low diffusion mobility metal (114a-c or 204a-c) may be either on the first top surface (108) or embedded in the first dielectric layer (207). The electric conductivity across the two conductive features (104, 106 or 214, 216) of the switching device (140 or 240) increases when a prescribed voltage is applied to the two conductive features (104, 106 or 214, 216). A method of forming such a switching device (140 or 240) is also provided.</p> |
