    摘要: Method, apparatus and plasma processing system for anisotropic etching of a substrate using a plasma. A high-frequency alternating electromagnetic field is generated using an inductive coupled plasma source, and a reactive gas or reactive gas mixture is exposed to that high-frequency alternating electromagnetic field in order to generate the plasma. The electrically charged particles of the plasma are accelerated onto the substrate. An aperture having at least one effective surface for electron-ion recombination is inserted between the plasma source and the substrate.

    摘要: A component having a robust, but acoustically sensitive microphone structure is provided and a simple and cost-effective method for its production. This microphone structure includes an acoustically active diaphragm, which functions as deflectable electrode of a microphone capacitor, a stationary, acoustically permeable counter element, which functions as counter electrode of the microphone capacitor, and an arrangement for detecting and analyzing the capacitance changes of the microphone capacitor. The diaphragm is realized in a diaphragm layer above the semiconductor substrate of the component and covers a sound opening in the substrate rear. The counter element is developed in a further layer above the diaphragm. This further layer generally extends across the entire component surface and compensates level differences, so that the entire component surface is largely planar according to this additional layer. This allows a foil to be applied on the layer configuration of the microphone structures exposed in the wafer composite, which makes it possible to dice up the components in a standard sawing process.
