Latest Patents
One of his latest patents is titled "Method for making a fuse structure for improved repaired yields on semiconductor memory devices." This invention introduces a novel fuse structure and method for deleting redundant circuit elements on integrated circuits. The fuse structure is designed to enhance the repair yield on RAM chips by eliminating defective rows of memory cells. The method involves creating a fuse area in a patterned electrically conducting layer, which is also used for forming interconnections. A thin insulating layer, measuring 0.4 um, is deposited uniformly across the substrate. The subsequent level of patterned interconnections is aligned over the fuse area to act as an etch-stop layer. This innovative process allows for the construction of fuse structures without the risk of overetching, which can lead to fuse damage. The uniform thickness of the insulating layer ensures reliable laser abrading to open the desired fuses.
