  • TOP CORNER ROUNDING OF DAMASCENE WIRE FOR INSULATOR CRACK SUPPRESSION
    Publication number: 20140035169
    Abstract: A structure and method for fabricating the structure that provides a metal wire having a first height at an upper surface. An insulating material surrounding said metal wire is etched to a second height below said first height of said upper surface. The metal wire from said upper surface, after etching said insulating material, is planarized to remove sufficient material from a lateral edge portion of said metal wire such that a height of said lateral edge portion is equivalent to said second height of said insulating material surrounding said metal wire.
    Type: Application
    Filed: September 16, 2013
