Patent ID: 8704327

Claim:
An integrated circuit, comprising: a first metallization level disposed on a substrate and separated from a second metallization level by an insulating region; a capacitive device having a thermally variable capacitive value and comprising: a thermally deformable assembly disposed within an enclosure, and comprising a beam held at least two different locations by at least two arms rigidly attached to edges of the enclosure, the beam and the arms being metal and disposed within the first metallization level; and an electrically-conducting fixed body; wherein a part of the said thermally deformable assembly forms a first electrode of the capacitive device; wherein a part of the said fixed body forms a second electrode of the capacitive device; wherein the said thermally deformable assembly has a plurality of configurations corresponding respectively to various temperatures of the said assembly and resulting in a plurality of distances separating the first electrode and second electrode and various capacitive values in the capacitive device corresponding to the plurality of distances; and wherein the said capacitive device is activatable for switching from one configuration to another.
