  • Patent number: 7696001
    Abstract: A method for mounting semiconductor chips on a substrate using flip-chip technology and a corresponding assembly are provided, which method includes the steps of: a) providing a semiconductor chip having a component region including components and an edge region, a mounting region containing a plurality of bonding pads being situated in the edge region; b) providing a substrate having a surface including a plurality of lands; c) applying soldering material to the bonding pads and/or to the lands; d) positioning the semiconductor chip on the substrate; and e) melting the soldering material by a soldering process in such a way that the mounting region of the semiconductor chip is moved towards the substrate due to the surface tension of the melting soldering material, and the component region is lifted away from the substrate by the resulting rotation around an axis of rotation or a pivot between the two regions.

  • Publication number: 20050253240
    Abstract: A micromechanical component including a chip which is mounted on a substrate and has an encapsulated chip area which is higher than its vicinity, as well as a mounting area provided in the vicinity of the encapsulated chip area. The chip being mounted on the substrate by a mounting arrangement which is connected to the mounting area, so that the encapsulated chip area faces the substrate and is positioned at a distance therefrom. The encapsulated chip area is surrounded by an underfill beneath the chip. A method for the manufacture of the micromechanical component is also provided.
