Pcm switch and method of making the same

A phase-change material (PCM) switch comprising:

• a resistive heating material;
• a PCM component proximal to the resistive heating material;
• a thermally conductive electrically insulating barrier layer positioned between the PCM component and the resistive heating material;
• a quench layer in contact with at least one of the resistive heating material and the PCM component, the quench layer being configured to dissipate heat associated with at least one of the resistive heating material and the PCM component;
• conductive lines extending from ends of the PCM component and control lines extending from ends of the resistive heating material.

A method for making a switch, the method comprising:

• forming an insulating layer over a substrate;
• forming a resistive heating material over the insulating layer;
• depositing a thermally conductive electrically insulating barrier layer over the heating material;
• forming a phase-change material (PCM) component over the barrier layer spaced apart and proximal to the resistive heating material;
• forming conductive lines from ends of the PCM component and control lines from ends of the resistive heating material;
• and
• forming a quench layer over the resistive heating material and the PCM component.
