Abstract
A process of fabricating a molecular electronic device that preserves the integrity of the active molecular layer of the electronic device during processing is described. In one aspect, a barrier layer is provided to protect a molecular layer sandwiched between a bottom wire layer and a top wire layer from degradation during patterning of the top wire layer. A molecular electronic device structure and a memory system that are formed from this fabrication process are described.

A molecular electronic device, comprising:
- a bottom wire layer;
- a molecular layer disposed over the bottom wire layer in a device region;
- a top wire layer disposed over the molecular layer in the device region;
- and
- a barrier layer defining the device region and having a thickness greater than a combined thickness of the molecular layer and the top wire layer.
A molecular memory system, comprising an array of molecular electronic devices, each molecular electronic device comprising:
- a bottom wire layer;
- a molecular layer disposed over the bottom wire layer in a device region;
- a top wire layer disposed over the molecular layer in the device region;
- and
- a barrier layer defining the device region and having a thickness greater than a combined thickness of the molecular layer and the top wire layer.
