Abstract: A semiconductor device for ambient sensing including: a cap traversed by a hole; and a main body mechanically coupled to the cap so as to delimit a cavity, which is interposed between the main body and the cap. The main body includes a semiconductor body and a coupling structure, which is interposed between the semiconductor body and the cap and laterally delimits a channel, which fluidically couples the cavity and the hole. The channel performs a mechanical filtering that is finer than the mechanical filtering performed by the hole.

Abstract: A method for manufacturing a semiconductor die, comprising the steps of: providing a MEMS device having a structural body, provided with a cavity, and a membrane structure suspended over the cavity; coupling the structural body to a filtering module via direct bonding or fusion bonding so that a first portion of the filtering module extends over the cavity and a second portion of the filtering module extends seamlessly as a prolongation of the structural body; and etching selective portions of the filtering module in an area corresponding to the first portion, to form filtering openings fluidically coupled to the cavity. The semiconductor die is, for example, a microphone.

Abstract: A microelectromechanical device having a first substrate of semiconductor material and a second substrate of semiconductor material having a bonding recess delimited by projecting portions, monolithic therewith. The bonding recess forms a closed cavity with the first substrate. A bonding structure is arranged within the closed cavity and is bonded to the first and second substrates. A microelectromechanical structure is formed in a substrate chosen between the first and second substrates. The device is manufactured by forming the bonding recess in a first wafer; depositing a bonding mass in the bonding recess, the bonding mass having a greater depth than the bonding recess; and bonding the two wafers.
