摘要： A component (1) is proposed wherein the suspension of the component (1) is effected in a stress-reduced manner. The component (1) can rest on a membrane (4) or be held by a spring element (2). The membrane (4) or the spring element (2) is situated above a depression (6) or an opening (7) partially spanned by the membrane (4). Preferably, the membrane (4) has a modulus of elasticity that is less than or equal to the modulus of elasticity of the component (1) or of the substrate (3). The component (1) can be covered with metal electrodes (10) wholly or partially over the area on two sides.

摘要： An electrical component has electrically conducting structures placed on an electrically isolating or semiconductive substrate and component structures sensitive to a voltage or an electrical arcing and galvanically separated from one another. To prevent an arcing between the galvanically separated component structures, the component structures are short-circuited with a shunt line having a smaller cross-section than the remaining electrical conductor tracks. The shunt lines can be burnt through by application of an electrical current at any given time, whereby a galvanic separation of the component structures is effected, if necessary, for the function of the component.

摘要： For a component operating with acoustic waves, it is proposed to arrange the electrode structure over a mechanically stable adaptation layer that serves to dissipate the electromechanical stresses. Further improvements of the output compatibility are achieved with additional intermediate layers and passivation layers applied on the sides or the entire surface over the electrode structure.

摘要： A liquid sensor has comb-shaped electrodes, applied to a piezoelectric substrate, as interdigital transducers for generating an electroacoustic wave from a transmitting transducer to a receiving transducer. The number of finger pairs of the interdigital transducers and the material out of which the electrodes are made are so chosen that a surface shear wave generated by the transmitting transducer and a bulk shear wave generated by the transmitting transducer have different frequencies.
