Fusible links with improved interconnect structure |
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.
