  • Patent number: 9708182
    Abstract: A method for producing at least one cavity within a semiconductor substrate includes dry etching the semiconductor substrate from a surface of the semiconductor substrate at at least one intended cavity location in order to obtain at least one provisional cavity. The method includes depositing a protective material with regard to a subsequent wet-etching process at the surface of the semiconductor substrate and at cavity surfaces of the at least one provisional cavity. Furthermore, the method includes removing the protective material at least at a section of a bottom of the at least one provisional cavity in order to expose the semiconductor substrate. This is followed by electrochemically etching the semiconductor substrate at the exposed section of the bottom of the at least one provisional cavity. A method for producing a micromechanical sensor system in which this type of cavity formation is used and a corresponding MEMS are also disclosed.

  • Publication number: 20050279382
    Abstract: A method for cleaning silicon-containing deposits in process chamber is described. Fluorine-containing compounds and additional compounds are used for the cleaning. The deposits are removed using a cleaning gas contains fluorine-containing compounds, at least 50% of which have more than one carbon atom and are C4F8 or C2F6 molecules, and additional compounds, at least 50% of which have at least one oxygen atom and at least 50% are N2O molecules. A pressure in the chamber is between 266 Pa and 665 Pa. The method permits economical and environmentally friendly cleaning of the process chamber.
