Abstract
An electrical interconnect is configured to provide an electrical connection between a first point and a second point. The interconnect includes a specular reflection layer adjacent a conductor layer. The conductor is configured to conduct electrons between the first and second points and the planar specular reflection layer confines the electrons to the conductor through specular reflection. This reduces electrical resistance of the electrical interconnect measured in a direction parallel with the specular reflection layer.
Claims21
An electrical interconnect configured to provide an electrical connection between a first point and a second point, comprising:
- a first specular reflection layer having a specularity of more than about 0.5;
- a second specular reflection layer having a specularity of more than about 0.5;
- and
- a conductor between the first and second specular reflection layers having a thickness of less than about 2 times the electron mean free path of the conductor, wherein the conductor is configured to conduct electrons between the first and second points and the first and second specular reflection layers confine the electrons to the conductor through specular reflection to thereby reduce electrical resistance of the electrical interconnect measured between the first and second points.
A method of making an electrical interconnect to produce an electrical connection between a first point and a second point, comprising:
- (a) depositing a first specular reflection layer, the first reflection layer having a specularity of more than about 0.5;
- (b) depositing a second specular reflection layer having a specularity of more than about 0.5;
- and
- (c) depositing a conductor between the first and second specular reflection layers having a thickness of less than about 2 times the electron mean free path of the conductor, wherein the conductor is configured to conduct electrons between the first and second points and the first and second specular reflection layers confine the electrons to the conductor through specular reflection to thereby reduce electrical resistance of the electrical interconnect measured between the first and second points in a direction parallel with the first and second planes, wherein the steps (a), (b) and (c) are carried out in any order.
An electrical interconnect configured to provide an electrical connection between a first point and a second point, comprising:
- a conductor extending between the first point and the second point, the conductor configured to conduct electrons therebetween;
- and
- specular reflection means forming an interface with the electrical conductor for reflecting and confining the electrons in the electrical conductor.
