摘要:
The invention relates to a method for producing a microphone, in which a transducer element (WE) is mounted on a carrier (TR); a cover is arranged over the transducer element (WE) and the carrier (TR) such that the transducer element (WE) is enclosed between the cover and the carrier (TR); a first sound inlet opening (S01) is produced in the carrier (TR); a functional test of the microphone is carried out; the first sound inlet opening (S01) is closed; and a second sound inlet opening (S02) is created in the cover. The present invention further relates to a microphone resulting from the method, in which the first sound inlet opening (S01) is prepared but closed.

On a carrier (1) an adhesion layer (4), an ASIC chip (2) and a sensor chip (3) are arranged one above another. An interchip connection (5) is provided for electrically connecting the chips among one another, and an ASIC connection (6) is provided for externally electrically connecting the circuit integrated in the ASIC chip.

A carrier substrate has a mounting location with a number of electrical connection pads on a top side and external contacts connected thereto on an underside. A metal frame encloses the connection pads of the mounting location. A MEMS chip has electrical contacts on an underside. The MEMS chip is placed on the mounting location of the carrier substrate in such a way that the MEMS chip is seated with an edge region of its underside on the metal frame. Using a flip-chip process, the electrical contacts of the MEMS chip are connected to the connection pads of the carrier substrate by means of bumps the metal frame is connected to the MEMS chip such that a closed cavity is formed between MEMS chip and carrier substrate.

A method is provided to produce a hermetic encapsulation for an electronic component, which may be an optical and at least partially light-permeable component or a surface wave component, comprises attaching and electrically contacting a component based on a chip to a carrier comprising electrical connection surfaces, such that a front of the chip bearing component structures facing the carrier is arranged to clear it, covering a back of the chip with a film made of synthetic material, such that edges of the film overlap the chip; tightly bonding the film and carrier in an entire edge region around the chip; structuring the film such that the film is removed around the edge region in a continuous strip parallel to the edge region; and applying a hermetically sealing layer over the film, such that this layer hermetically terminates with the carrier in a contact region outside of the edge region.

摘要:
The present invention relates to an encapsulated component that includes a carrier substrate and at least one chip positioned on the top of the carrier substrate and electrically connected to it by means of electrically conductive connections. The encapsulation of the chip is accomplished with a seal or dielectric layer. As a result of differing coefficients of expansion of the seal or dielectric layer and the electrically conductive connections, with changing temperatures stresses occur in the electrically conductive connections, which can lead to cracks, breaks and even to interruption of the electrically conductive connections. To mechanically relieve the electrically conductive connections of stresses from changing temperatures (in particular under extreme thermal loads), it is proposed that the carrier substrate be provided with a support element that encircles the chip, which serves to support the seal or dielectric layer, and/or that the material and the arrangement of the encapsulation be selected accordingly.

A micro electro-mechanical systems (MEMS) package is described herein. The package includes a carrier substrate having a top side, a MEMS chip mounted on the top side of the carrier substrate, and at least one chip component on or above the top side of the carrier substrate or embedded in the carrier substrate. The package also includes a thin metallic shielding layer covering the MEMS chip and the chip component and forming a seal with the top side of the carrier substrate.
