Abstract
Antifuses in PROM and FPGA applications have used silicon and/or polycrystalline silicon electrodes. Metal electrode antifuses have the lowest resistance and lowest capacitance among programmable interconnect structures. The ViaLink, a metal electrode amorphous silicon antifuse, has been used as a programmable interconnect device for a FPGA. This paper describes for the first time, the composition, structure, electrical characteristics, and temperature dependence of the conducting filament in the programmed TiW electrode amorphous silicon antifuse.> Author(s) Gordon, K.E.
