Abstract
A programmable interconnect structure and method of operating the same provides a programmable interconnection between electrical contacts. The interconnect includes material that has a reversibly programmable resistance. The material includes a molecular matrix with ionic complexes distributed through the molecular matrix. Application of an electrical field or electric current causes the molecular composite material to assume a desired resistivity (or conductivity) state. This state is retained by the molecular composite material to thus form a conductive or a non-conductive path between the electrical contacts.
Claims22
A semiconductor device, comprising:
- a first electrical contact;
- a second electrical contact;
- an interconnect between the first and second electrical contacts, the interconnect comprises a molecular matrix with ionic complexes distributed there through and has a reversibly programmable resistance and extends into a via hole to connect the first electrical contact and the second electrical contact;
- and
- wherein the ionic complexes are dissociable in the molecular matrix under the influence of an appiled electrical field.
A programmable interconnect structure comprising:
- first and second electrical contacts;
- and
- an interconnect between the first and second electrical contacts that extends into a via to selectively permit contact between the first and second electrical contacts and comprises a single layer of material that has a reversibly programmable resistivity, the material comprising a molecular matrix with ionic complexes distributed throughout the molecular matrix, wherein the ionic complexes are dissociable in the molecular matrix under the influence of an applied field.
