Abstract
A neuromorphic semiconductor device includes a copper-based intercalation channel disposed on an insulative layer, a source contact and a drain contact of a substrate. A copper-based electrolyte layer is disposed on the copper-based intercalation channel and a copper-based gate electrode is disposed on the copper-based electrolyte layer.
Claims20
A method of manufacturing a semiconductor device, comprising:
- forming a copper-based intercalation channel on an insulative layer, a source contact and a drain contact of a substrate;
- forming a copper-based electrolyte layer on the copper-based intercalation channel;
- and
- forming a copper-based gate electrode on the copper-based electrolyte layer.

An analog switching device, comprising:
- a source contact and a drain contact disposed on an insulative layer of a substrate;
- a copper-based intercalation channel disposed on the insulative layer, the source contact and the drain contact, the copper-based intercalation channel having variable resistivity as a function of copper content;
- a copper-based solid electrolyte disposed on the copper-based intercalation channel;
- and
- a copper-based gate electrode disposed on the copper-based solid electrolyte layer, the copper-based gate electrode configured to act as a copper ion reservoir for tuning the analog switching device via intercalation of the copper-based intercalation channel.
