Abstract
A semiconductor device includes: a substrate; a transduction microstructure integrated in the substrate; a cap joined to the substrate and having a first face adjacent to the substrate and a second, outer, face; and a channel extending through the cap from the second face to the first face and communicating with the transduction microstructure. A protective membrane made of porous polycrystalline silicon permeable to aeriform substances is set across the channel.
