    摘要: The fuse link includes a first and second interconnect, with interconnects each being substantially longer than deep. The interconnects are disposed toward each other with a insulator region between them. A fusible conductor, spanning the insulator region, is attached at the top of the interconnects. The present device allows the length of the fusible conductor to be shortened, and results in a fuse link that can be consistently blown with a single laser pulse. Additionally, the fuse link can be used in a staggered layout. The staggered layout of parallel fuse links allows a high number of links in a relatively small area, with or without the use of tungsten barriers, and allows accessing all fuse links through a single fuse blow window.

    摘要: The present disclosure sets forth an improved integrated circuit in which circuit elements, adjacent to a fuse, are protected by barriers positioned adjacent the fuse. In the improved integrated circuit the barriers are non-frangible, high melting point structures buried in the passivating layer, covering a wiring layer containing a fuse, and are between the fuse and adjacent circuit elements in the wiring layer structures.Also taught is a method of protecting circuit elements adjacent a fuse comprising the steps of depositing an insulating layer on the surface of a semiconductor device having active regions therein, forming a plurality of fuses and circuit elements in said layer, coating said fuses and elements with a second insulating layer, patterning said second insulating layer to form grooves between each of said fuses and any adjacent fuse or circuit element, and depositing a high melting point and non-frangible material in said grooves.
