Structures for packaging stress-sensitive micro-electro-mechanical system stacked onto electronic circuit chip
A packaged micro-electro-mechanical system (MEMS) device (100) comprises a circuitry chip (101) attached to the pad (110) of a substrate with leads (111), and a MEMS (150) vertically attached to the chip surface by a layer (140) of low modulus silicone compound. On the chip surface, the MEMS device is surrounded by a polyimide ring (130) with a surface phobic to silicone compounds. A dome-shaped glob (160) of cured low modulus silicone material covers the MEMS and the MEMS terminal bonding wire spans (180); the glob is restricted to the chip surface area inside the polyimide ring and has a surface non-adhesive to epoxy-based molding compounds. A package (190) of polymeric molding compound encapsulates the vertical assembly of the glob embedding the MEMS, the circuitry chip, and portions of the substrate; the molding compound is non-adhering to the glob surface yet adhering to all other surfaces.

Auxetic interposer for microelectromechanical systems (MEMS) device and MEMS device package including the same
An auxetic interposer includes: a frame enclosing an interior space; a pad arranged within the interior space; and a plurality of micro auxetic lattices extending between the frame and the pad.
MEMS device including a capacitive pressure sensor and manufacturing process thereof
MEMS device, in which a body made of semiconductor material contains a chamber, and a first column inside the chamber. A cap of semiconductor material is attached to the body and forms a first membrane, a first cavity and a first channel. The chamber is closed on the side of the cap. The first membrane, the first cavity, the first channel and the first column form a capacitive pressure sensor structure. The first membrane is arranged between the first cavity and the second face, the first channel extends between the first cavity and the first face or between the first cavity and the second face and the first column extends towards the first membrane and forms, along with the first membrane, plates of a first capacitor element.
Multi-layer sealing film for high seal yield
A multi-layer sealing film for high seal yield is provided. In some embodiments, a substrate comprises a vent opening extending through the substrate, from an upper side of the substrate to a lower side of the substrate. The upper side of the substrate has a first pressure, and the lower side of the substrate has a second pressure different than the first pressure. The multi-layer sealing film covers and seals the vent opening to prevent the first pressure from equalizing with the second pressure through the vent opening. Further, the multi-layer sealing film comprises a pair of metal layers and a barrier layer sandwiched between metal layers. Also provided is a microelectromechanical systems (MEMS) package comprising the multilayer sealing film, and a method for manufacturing the multi-layer sealing film.
