摘要： A method for operating a semiconductor gas sensor. The semiconductor gas sensor has a sensor element with a sensor material having a semiconductor, a plurality of measuring electrodes electrically connected to the sensor material for exciting and reading the sensor material, and a control and evaluation device for generating excitation signals and evaluating read measurement signals. A surface of the sensor material is exposed to a gaseous medium. In the method, a first excitation signal and a second excitation signal are applied to the sensor material. The excitation signals have different excitation frequencies. A first measurement signal is read based on the first excitation signal, and a second measurement signal is read based on the second excitation signal. A sensor signal is ascertained based on the excitation signals and the measurement signals.

摘要： A method of assessing galvanic electronic isolation of two components at a joint of the two components includes measuring a first electrical resistance at a first condition across a joint of two components and comparing the first electrical resistance to a threshold resistance. The comparison of the first electrical resistance to the threshold resistance is indicative of a degree of electrical isolation of the two components. A second electrical resistance is measured at a second condition and the second electrical resistance is compared to the first electrical resistance. The result of the comparison of the second electrical resistance to the first electrical resistance is indicative of a type of electrical connection between the two components.

摘要： It is disclosed herein a semiconductor device and a method of manufacturing the semiconductor device. The semiconductor device is made using partly CMOS or CMOS based processing steps, and it includes a semiconductor substrate, a dielectric region over the semiconductor substrate, a heater within the dielectric region and a patterned layer of noble metal above the dielectric region. The method includes the deposition of a photoresist material over the dielectric region, and patterning the photo-resist material to form a patterned region over the dielectric region. The steps of depositing the photo-resist material and patterning the photo-resist material may be performed in sequence using similar photolithography and etching steps to those used in a CMOS process. The resulting semiconductor device is then subjected to further processing steps which ensure that a dielectric membrane and a metal structure within the membrane are formed in the patterned region over the dielectric region.

摘要： An environmental conditioning assembly for use in mechanical testing at scales of microns or less. The assembly includes an enclosure housing with an environmental cavity therein. A sample stage is positioned within the environmental cavity and includes an option sample heater. The enclosure housing includes a cavity perimeter clustered around the sample stage, and the enclosure housing isolates the environmental cavity and the sample stage from an environment exterior to the enclosure housing. In an example, an expansion and contraction linkage maintains a sample on the sample stage at a static elevation according to heating or cooling fluctuations within the environmental cavity. A testing instrument access port extends through the enclosure housing into the environmental cavity.
