Abstract:
1. A semiconductor structure comprising: a first isolation structure having a top surface; a plurality of conductive landing pads, the plurality of conductive landing pads being spaced apart and having a plurality of top surfaces, each conductive landing pad having a bottom surface, all the bottom surface of each of the plurality of conductive landing pads touching the first isolation structure; a first metallic structure that touches the top surface of the first isolation structure and the plurality of top surfaces of the plurality of conductive landing pads, the first metallic structure having a top surface and a bottom surface, the top surface of the first metallic structure having a shape; a second isolation structure that touches the top surface of the first metallic structure, the second isolation structure having a top surface; and a second metallic structure that touches the top surface of the second isolation structure and lies directly over all of the first metallic structure, the second metallic structure having a top surface, the top surface of the second metallic structure having a shape that is substantially identical to the shape of the top surface of the first metallic structure.
