  • Integrated two-terminal fuse-antifuse and fuse and integrated two-terminal fuse-antifuse structures incorporating an air gap
    Patent number: 5903041
    Abstract: A two-terminal fuse-antifuse structure comprises a horizontal B-fuse portion and a vertical A-fuse portion disposed between two metallization layers of an integrated circuit device. The two-terminal fuse-antifuse can be programmed with a relatively high current applied across the two terminals to blow the B-fuse, or with a high voltage applied across the two terminals to program the A-fuse. Such a device, connected between two circuit nodes, initially does not provide an electrical connection between the two circuit nodes. It may then be programmed with a relatively high voltage to blow the A-fuse, causing it to conduct between the two circuit nodes. Then, upon application of a relatively high current between the two circuit nodes, the B-fuse will blow, making the device permanently non-conductive.
