ABSTRACT:
Reconfigurable devices and methods for the fabrication thereof are provided. In one aspect, a reconfigurable device is provided. The reconfigurable device comprises a substrate; a first dielectric layer on the substrate; a conductive layer recessed into at least a portion of a side of the first dielectric layer opposite the substrate; at least one second dielectric layer over the side of the first dielectric layer opposite the substrate, so as to cover the conductive layer; a heater within the second dielectric layer; at least one programmable via extending through the second dielectric layer, extending through and surrounded by the heater and in contact with the conductive layer, the programmable via comprising at least one phase change material; a capping layer over the programmable via; a first conductive via and a second conductive via, each extending through the second dielectric layer and in contact with the heater; and a third conductive via extending through the second dielectric layer and in contact with the conductive layer.
