Abstract (en)

[origin: WO2016050932A1] The invention relates to a method for producing a closed cavity on a substrate, comprising the steps consisting of: a) forming a cavity (5a) surrounded by at least one block on a given face of a substrate (1), the cavity having an aspect ratio h/cd higher than a determined threshold, and b) depositing a closing layer (20) on the at least one block surrounding the cavity, the aspect ratio of the cavity being such that in step b), the closing layer does not entirely fill said cavity and an empty space in the cavity is maintained.
