  • Patent number: 7589363
    Abstract: A structure configured to disconnect circuit elements. The structure generally includes a dielectric layer over a light-absorbing structure, and a lens over the dielectric layer and the light-absorbing structure, configured to at least partially focus light onto the light-absorbing structure. The light-absorbing structure absorbs a first wavelength of light with a minimum threshold efficiency, the lens is substantially opaque to the first wavelength of light, and the dielectric layer is substantially transparent to the first wavelength of light. The structure advantageously provides improved reliability and smaller chip area, thereby increasing the yield of the manufacturing process and the numbers of die per wafer (both gross and good).

  • Patent number: 7344924
    Abstract: A fuse structure, an integrated circuit including the structure, and methods for making the structure and (re)configuring a circuit using the fuse. The fuse structure generally includes (a) a conductive structure with at least two circuit elements electrically coupled thereto, (b) a dielectric layer over the conductive structure, and (c) a first lens over both the first dielectric layer and the conductive structure configured to at least partially focus light onto the conductive structure. The method of making the structure generally includes the steps of (1) forming a conductive structure electrically coupled to first and second circuit elements, (2) forming a dielectric layer thereover, and (3) forming a lens on or over the dielectric layer and over the conductive structure, the lens being configured to at least partially focus light onto the conductive structure.
