Commutator structure comprising several channels of phase change material and interdigitated control electrodes

Device capable of routing or interrupting a connection between at least one first conducting element and at least one second conducting element resting on a support, said device including:

• at least one phase change material arranged between the first conducting element and the second conducting element, the phase change material being capable of changing state between a crystalline state wherein the phase change material has a first resistivity and an amorphous state wherein the phase change material has a second resistivity higher than the first resistivity, in such a way that when the phase change material is in the crystalline state it enables the routing of a first signal between the first conducting element and the second conducting element, when the phase change material is in the amorphous state it prevents the routing of the first signal between the first conducting element and the second conducting element,
• means of heating the phase change material provided with at least one first electrode and at least one second electrode, the means of heating being capable of modifying the state of the phase change material by Joule effect by injecting at least one electrical activation signal between the first electrode and the second electrode,
• at least one first zone of phase change material and at least one second zone of phase change material being comprised between the first conducting element and the second conducting element, the first zone of phase change material and the second zone of phase change material being arranged on either side and in contact with a conducting portion of a given electrode among said first electrode and second electrode, the first zone of phase change material being intercalated between said conducting portion of the given electrode and a conducting portion of another electrode among said first electrode and second electrode, the second zone of phase change material being intercalated between said conducting portion of the given electrode and a conducting portion of another electrode among said first electrode and second electrode.
