Abstract:
A thermal sensor, comprisinga silicon element; at least one contact column; a largely self-supporting membrane layer including at least one sensor element, wherein the membrane layer is spaced from the silicon element by the at least one contact column and is largely supported by the at least one contact column, and wherein the at least one contact column forms an electrical contact with the at least one sensor element; and an electronic circuit, wherein: the at least one contact column corresponds to at least two electrical contact columns, and the at least one sensor element is electrically connected via the at least two electrical contact columns to the electronic circuit; wherein the at least one contact column includes thermal contact columns and electrical contact columns, wherein the at least one sensor element is electrically connected to the electronic circuit via the electrical contact columns, and wherein the at least one sensor element is electronically insulated from the electronic circuit by the thermal contact columns.
