  • Patent number: 9917055
    Abstract: A corrosion-resistant semiconductor device includes fuse elements that can be cut by laser light. An upper portion of the fuse elements is covered with a porous insulating film so that, when laser light irradiated from a rear surface of a semiconductor substrate is collected at selected fuse elements, the fuse elements generate heat, expand, and rupture. An array of intersecting metal lines forming windows is disposed over the fuse elements to permit rapid expansion of the fuse elements when irradiated with the laser light. A silicon nitride film having a uniform thickness is formed on a front surface of the semiconductor device to prevent entry of moisture.

  • Patent number: 9911694
    Abstract: Embodiments of the invention describe low capacitance interconnect structures for semiconductor devices and methods for manufacturing such devices. According to an embodiment of the invention, a low capacitance interconnect structure comprises an interlayer dielectric (ILD). First and second interconnect lines are disposed in the ILD in an alternating pattern. The top surfaces of the first interconnect lines may be recessed below the top surfaces of the second interconnect lines. Increases in the recess of the first interconnect lines decreases the line-to-line capacitance between neighboring interconnects. Further embodiments include utilizing different dielectric materials as etching caps above the first and second interconnect lines. The different materials may have a high selectivity over each other during an etching process. Accordingly, the alignment budget for contacts to individual interconnect lines is increased.
