Abstract:
1. A method, comprising: defining a first via in a first dielectric layer; forming a first conductive material within the first via; forming a second dielectric layer over the first dielectric layer; defining a second via in the second dielectric layer aligned within the first via and leading to the first conductive material, thereby exposing a portion of the first conductive material; reacting the exposed portion of the first conductive material with at least one fluid species by way of the second via thereby forming a reacted portion of the first conductive material; and forming a second conductive material within the second via in electrical contact with the reacted portion of the first conductive material, the second conductive material being selected from the group consisting of Tantalum (Ta), Tantalum Nitride (TaN wherein the first conductive material, the reacted portion of the first conductive material, and the second conductive material define a memristor.
