  • SEMICONDUCTOR FUSES IN A SEMICONDUCTOR DEVICE COMPRISING METAL GATES
    Publication number: 20130140645
    Abstract: In a replacement gate approach, the semiconductor material of the gate electrode structures may be efficiently removed during a wet chemical etch process, while this material may be substantially preserved in electronic fuses. Consequently, well-established semiconductor-based electronic fuses may be used instead of requiring sophisticated metal-based fuse structures. The etch selectivity of the semiconductor material may be modified on the basis of ion implantation or electron bombardment.
