  • Patent number: 7719125
    Abstract: The detachment of a semiconductor chip (1) from a foil (4) and picking the semiconductor chip (1) from the foil (4) takes place with the support of a chip ejector (6), that has a ramp (16), the surface (17) of which is formed concave and ends at a stripping edge (18) projecting from the surface (9) of the chip ejector (6), and a support area (13) with grooves (12) arranged next to the stripping edge (18). Vacuum can be applied to the grooves (12). The detachment and picking of the semiconductor chip (1) from the foil (4) takes place in that the wafer table (5) is shifted relative to the chip ejector (6) in order to pull the foil (4) over the stripping edge (18) protruding from the surface (9) of the chip ejector (6), whereby the semiconductor chip (1) temporarily detaches itself at least partially from the foil (4) and lands on the foil (4) above the support area (13), and in that the chip gripper (7) picks the semiconductor chip (1) presented on the support area (13).

  • Patent number: 7714441
    Abstract: A microelectronic topography includes a dielectric layer (DL) with a surface higher than an adjacent bulk metal feature (BMF) and further includes a barrier layer (BL) upon the BMF and extending higher than the DL. Another microelectronic topography includes a BL with a metal-oxide layer having a metal element concentration which is disproportionate relative to concentrations of the element within metal alloy layers on either side of the metal-oxide layer. A method includes forming a BL upon a BMF such that portions of a first DL adjacent to the BMF are exposed, selectively depositing a second DL upon the BL, cleaning the topography thereafter, and blanket depositing a third DL upon the cleaned topography. Another method includes polishing a microelectronic topography such that a metallization layer is coplanar with a DL and further includes spraying a deionized water based fluid upon the polished topography to remove debris from the DL.

  • Patent number: 7692315
    Abstract: In a pad forming region electrically connecting an element forming region to the outside, in which a low dielectric constant insulating film is formed in association with in the element forming region, a Cu film serving as a via formed in the low dielectric constant insulating film in the pad forming region is disposed in higher density than that of a Cu film serving as a via in the element forming region. Hereby, when an internal stress occurs, the stress is prevented from disproportionately concentrating on the via, and deterioration of a function of a wiring caused thereby can be avoided.

  • Patent number: 7675180
    Abstract: A film-on-wire spacer covers an entire upper surface of a lower electronic component. Accordingly, an upper electronic component is supported above bond pads and lower bond wires of the lower electronic component. This decreases the stress on the upper electronic component, e.g., during wirebonding, and thus decreases the chance of cracking the upper electronic component. Further, the lower bond wires are enclosed in and protected by the film-on-wire spacer. Further, the film-on-wire spacer is thin resulting in a minimum height of the stacked electronic component package.

  • Patent number: 7663248
    Abstract: A flip-chip component includes a chip with pads located on the chip and a chip frame, wherein the chip frame is arranged around the chip and is attached to the chip so that the active surface of the chip is substantially planar with a surface of the chip frame. A redistribution layer is attached to the chip and chip frame, and interconnections mechanically connect the redistribution layer and a board. Aspects of the invention improve the reliability of the flip-chip package by reducing shear stresses in the interconnections between the package and a board during changing temperatures. This is achieved by carefully selecting the material of the chip frame and designing the placement of the interconnections so that thermal expansion of the package matches that of the board during changing temperatures.
