Abstract: The gas sensor has a selectively permeable membrane which is composed of silicon material and is provided with a heating device on the outside. The membrane closes an evacuated housing which contains a pressure sensor. When evacuating the area surrounding the housing, the heat dissipation is changed as a result of the quick change in the total pressure of the surrounding air, with the result that signal drift arises despite temperature regulation of the membrane. The disclosure provides at least one second heating device whose temperature is regulated independently of the first heating device. As a result, the membrane temperature is highly constant even in the case of severely changing total pressure in the housing.

Abstract: A reversible fuse structure in an integrated circuit is obtained through the implementation of a fuse cell having a short thin line of phase change materials in contact with via and line structures capable of passing current through the line of phase change material (fuse cell). The current is passed through the fuse cell in order to change the material from a less resistive material to a more resistive material through heating the phase change material in the crystalline state to the melting point then quickly quenching the material into the amorphous state. The reversible programming is achieved by passing a lower current through the fuse cell to convert the high resistivity amorphous material to a lower resistivity crystalline material. Appropriate sense-circuitry is integrated to read the information stored in the fuses, wherein said sense circuitry is used to enable or disable circuitry.
