Abstract
A thermally deformable assembly is formed in an integrated-circuit metallization level. The physical behavior of the metal forming the assembly brings the assembly into contact with a stop-forming body when subjected to a temperature change caused by a current flow. A natural rollback to the initial configuration in which the assembly is a certain distance away from the body is prevented. The state or configuration of the assembly is determined by a capacitive reader.
