Abstract (en)

[origin: WO2005118463A1] The invention relates to a micromechanical component having at least two caverns, in which the caverns are delimited by a micromechanical part and by a cap, and the caverns have different atmospheric internal pressures. The invention also relates to a method for producing a micromechanical component having at least two caverns, in which the caverns are delimited by a micromechanical part and by cap. To this end, the micromechanical part and the cap are hermetically joined to one another at a first predeterminable atmospheric pressure. Afterwards, an entrance to at least one cavern is made, and the entrance is then hermetically closed at a second predeterminable atmospheric pressure.
