  • Patent number: 9704839
    Abstract: A semiconductor device includes an active region disposed in a semiconductor substrate and an uppermost metal level including metal lines, where the uppermost metal level is disposed over the semiconductor substrate. Contact pads are disposed at a major surface of the semiconductor device, where the contact pads are coupled to the metal lines in the uppermost metal level. An isolation region separates the contact pads disposed at the major surface. Adjacent contact pads are electrically isolated from one another by a portion of the isolation region. Reflective structures are disposed between the upper metal level and the contact pads, where each of the reflective structures that is directly over the active region completely overlaps an associated portion of the isolation region separating the contact pad.
    Type: Grant

  • Publication number: 20140319689
    Abstract: A chip contact pad and a method of making a chip contact pad are disclosed. An embodiment of the present invention includes forming a plurality of contact pads over a workpiece, each contact pad having lower sidewalls and upper sidewalls and reducing a lower width of each contact pad so that an upper width of each contact pad is larger than the lower width. The method further includes forming a photoresist over the plurality of contact pads and removing portions of the photoresist thereby forming sidewall spacers along the lower sidewalls.
