Abstract
In an integrated circuit having interconnecting lines formed on an insulated layer deposited on a semiconductor substrate which provide connections between elements integral to the integrated circuit, a fuse structure programmable by a laser beam that includes: a melt-away elongated fuse link joining two segments of an interconnecting line; a plurality of fins integral and coplanar to the fuse link, each of the fins transversally extending away from the fuse link for absorbing energy emitted by the laser beam; and a reflecting plate positioned underneath the fuse link to reflect energy provided by the laser beam back into the fuse link, such that both the combination of the fins and the reflecting plate reduces the energy emitted by the laser beam required to blow the fuse structure.
