摘要： A method and structure for a fuse structure comprises an insulator layer, a plurality of fuse electrodes extending through the insulator layer to an underlying wiring layer, an electroplated fuse element connected to the electrodes, and an interface wall. The fuse element is positioned external to the insulator, with a gap juxtaposed between the insulator and the fuse element. The interface wall further comprises a first side wall, a second side wall, and an inner wall, wherein the inner wall is disposed within the gap. The fuse electrodes are diametrically opposed to one another, and the fuse element is perpendicularly disposed above the fuse electrodes. The fuse element is either electroplatted, electroless plated, or is an ultra thin fuse.

摘要： A method of repeatedly exposing a pattern across a wafer in a sequential stepping process is disclosed. The pattern that is exposed includes at least one alignment mark. Each time the exposing process is repeated, the current exposure overlaps a portion of the wafer where the pattern was previously exposed and thereby erases a previously exposed alignment mark by re-exposing an area of the wafer where the previously exposed alignment mark was located. After the exposing process is repeated across the wafer, alignment marks remain only in the last exposed areas of the wafer.
