摘要： A gas sensor has a gas-sensitive layer with a surface area where the electron affinity depends on the concentration of a target gas brought in contact with the surface area. An electrical potential sensor is capacitively coupled to the surface area via an air gap. The surface area of the gas-sensitive layer is covered by an electric insulating layer that is inert to the target gas and is bonded to the gas-sensitive layer. The coating is designed in such a way that it is permeable for the target gas and a different, non-target gas that can be adsorbed on the surface area. The coating has different diffusion constants for the target gas and the non-target gas. The diffusion constants are coordinated with each other in such a way that the sensitivity of the gas sensor to the target gas increases when the target gas concentration exceeds a predetermined concentration threshold in the presence of the non-target gas.

摘要： A gas sensor has at least one gas sensitive layer, which has at least one surface area in which the work function is dependent upon the concentration of a target gas capable of being brought into contact with the surface zone. At least one electric potential sensor is capacitatively coupled to the surface zone over an air gap. The surface zone of the gas sensitive layer is covered with an electrically insulating coating which is inert to the target gas and which is adhesively bound to the gas sensitive layer. The coating is configured so that it is permeable to the target gas and so that when the target gas contacts the surface zone of the gas sensitive layer, it prevents or at least impedes an alteration of the bound state of atoms and/or molecules bound to the surface zone and differing from the target gas.

摘要： The invention relates to a moisture sensor which comprises a receiving area on its surface for a moisture film, the layer thickness of which is dependent on the relative humidity in the surrounding of the receiving area. The moisture sensor has a signal source which is connected to at least one control electrode at at least one infeed, the electrode abutting the receiving area, for providing a control voltage to the moisture film. The moisture sensor comprises at least one potential sensor which has at least one sensor area, under the receiving area, which is spaced apart from the at least one infeed. The sensor area is electrically insulated from the receiving area by an insulation layer, located between the sensor area and the receiving area, in such a way that an electrical potential can be capacitively detected by means of the potential sensor, the potential being dependent on the layer thickness of the moisture film and the control voltage.

摘要： In a procedure for measuring the concentration of a target gas, a gas sensor is provided whose sensor signal at constant temperature is dependent on a target gas concentration and has a lower measurement sensitivity in a first modulation range than in a second modulation range. The position of the modulation ranges is dependent on the temperature. The temperature of the gas sensor is controlled so that the sensor signal is essentially independent of the target gas concentration and lies within the second modulation range. The temperature of the gas sensor is then a measurement for the target gas concentration.

摘要： The invention relates to a sensor for measuring a gas concentration or ion concentration having a substrate (11); a drain (3) fashioned on the substrate; a source (2) fashioned on the substrate; a channel region (4) of the substrate, which is arranged between drain (3) and source (2); a conductive guard ring (1), which is arranged outside the channel region; a sensitive gate layer (8) whose potential depends on an ambient gas concentration or ion concentration, there being an air gap (10) between the gate layer and the channel region (4). In order to create a sensor that can be manufactured at low cost, has small dimensions, and nevertheless guarantees a high accuracy of measurement for the change in concentration as a function of time, it is provided that a ring structure (20) made of a different surface material having a surface conductivity lower than that of the rest of the surface region is fashioned between the guard ring (1) and the channel region (4).

摘要： A semiconductor memory includes non-volatile memory cells which can be electrically programmed and erased by means of tunnel current (EEPROM) with a floating-gate transistor, the cell being arranged in memory cell groups of n lines and m columns each, n cells being connected in series, which serial connection forms the bit line for the columns of a cell block. The control gate is common to m memory cells of one line of the cell block situated next to one another and forms the word line for the line in the memory cell group. The floating gate does not extend over the entire width of the channel, so that in each memory cell a parallel transistor is formed which is connected in parallel to the floating-gate transistor and is controlled only by the control gate, which parallel transistor is conducting during reading for each non-selected cell. As a result, the problem of over-erasing is solved even in the case of short access times, without an additional access transistor being required.
