Abstract
The present invention provides microelectronic electrochemical structures and related fabrication methods. A composite microelectronic structure is provided that includes first and second conductors dielectrically isolated from one another at a crossing thereof, the crossing surrounded by a dielectric material. A portion of the dielectric material around the crossing of the first and second conductors is removed to form a well that exposes respective outer surfaces of the first and second conductors and a molecule is deposited in the well such that the deposited molecule contacts the exposed outer surfaces of the first and second conductors.
Claims32
A microelectronic electrochemical cell, comprising:
- first and second crossing conductors that cross at a crossing and are separated by a first intervening dielectric layer on a substrate;
- and
- a second dielectric layer on the substrate that defines a well around the crossing that exposes respective outer surfaces of the first and second conductors.
A microelectronic electrochemical cell, comprising:
- a first conductor on a substrate;
- a first dielectric layer on the first conductor;
- a second conductor on the first dielectric layer such that the first and second conductors cross at a crossing;
- and
- a second dielectric layer on the substrate that defines a well around the crossing that exposes respective outer surfaces of the first and second conductors.
A memory cell, comprising:
- first and second crossing conductors that cross at a crossing and are separated by an first intervening dielectric layer on a substrate;
- and
- a second dielectric layer on the substrate that defines a well around the crossing that exposes respective outer surfaces of the first and second conductors.
An assay, comprising:
- first and second crossing conductors that cross at a crossing and are separated by an first intervening dielectric layer on a substrate;
- and
- a second dielectric layer on the substrate that defines a well around the crossing that exposes respective outer surfaces of the first and second conductors.
