  • Publication number: 20140111062
    Abstract: A hermetic wafer-level package composed of two piezoelectric wafers, preferably identical in terms of material, and a production method therefor are presented. The electrical and mechanical connection between the two wafers is accomplished with frame structures and pillars, the partial structures of which, distributed between two wafers, are wafer-bonded with the aid of connecting layers.

  • Publication number: 20140036466
    Abstract: The invention relates to a cased electrical component comprising a carrier substrate (10), a spring device (20), which is arranged on the carrier substrate (10), a chip (30), which on a first side (31) of the chip is coupled to the spring device (20), and a cover element (100), which is arranged on the carrier substrate (10). The cover element (100) is arranged over the chip (20) such that the cover element (100) is in contact with the chip (30) at least on a second side (32) of the chip, which is different from the first side. The component has a low space requirement and is highly sealed with respect to influences from the surroundings.

  • Publication number: 20100116531
    Abstract: A component having a multilayer solderable or bondable connecting surface on a substrate is proposed, which, in addition to the electrically conductive pad metallization and the UBM metallization also has an electrically conductive stress compensation layer that is arranged between the substrate and the pad metallization or between the pad metallization and the UBM metallization. The insensitivity to stress of the connecting metallization is achieved by means of a stress compensation layer whose modulus of elasticity is less than that of the UBM metallization.

  • Patent number: 7518249
    Abstract: A component includes a carrier substrate having a coefficient of thermal expansion ?p and a chip mounted on the carrier substrate by a plurality of bumps. The chip has a first coefficient of thermal expansion ?1 in a first direction x1 and a first expansion difference, ??1 equal to the absolute value of ?p??1. The chip also has a second coefficient of thermal expansion ?2 in a second direction x2 and a second expansion difference ??2 is equal to the absolute value of ?p??2,. The bumps are arranged such that a first distance, ?x1, corresponding to a normal projection of a line between centers of terminally situated bumps in the first direction onto an axis running parallel to direction x1 is less than a second distance corresponding to a normal projection of a line between centers of terminally situated bumps in the second direction onto an axis parallel to direction x2.

  • Patent number: 7388281
    Abstract: 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.

  • Patent number: 6982380
    Abstract: For simpler and safer encapsulation of components, it is proposed to generate the connection between a chip and a carrier substrate by means of bump connections that are sunk into recesses on the carrier substrate. The component thereby lies directly on the carrier substrate, in particular on a frame circumscribing the component structures on the chip.
