Abstract (en)

[origin: WO2006008412A1] The invention relates to a method for testing the tightness of a MEMS or of a small encapsulated component, the MEMS or small component being mounted in a cavity of a support. Said cavity is closed by sealing means and contains a gas having a density different than that if it were at the pressure of the medium outside of the cavity. The method comprises a step for measuring the density of the gas contained inside the cavity.
