Abstract
An antifuse structure particularly suitable for field programmable gate arrays is presented. In most present day processes the antifuse structure is formed with a refractory metal layer, amorphous silicon layer and refractory metal layer sandwiched between two metal interconnection lines. Unprogrammed resistances of very high values, programmed resistances of very low values, short programming times and desirable programming voltages are among the advantages realized.
