Abstract (en)

[origin: WO2009127670A1] In order to improve a programmable antifuse transistor (100), in particular an n-channel MOS transistor, and a method for programming at least one of said antifuse transistors (100), comprising - at least one gate (G) with a gate terminal (12), - at least one source (S) with a source terminal (14), - at least one drain (D) with a drain terminal (16) and - at least one substrate (10) with a substrate terminal (18), in such a way that active circuits/circuit elements do not have to be located at a significant distance from the antifuse, thereby minimizing the space requirements, without any additional process steps being needed, it is proposed that the level of the potential difference between the source terminal (14) and the substrate terminal (18) is no more than about 0.5 volts, in particular no more than about 0.3 volts, that the drain terminal (16) and the source terminal (14) lie at different potentials and that by adjusting the drain-source voltage and/or the gate-source voltage between source (S) and drain (D) a flow of charge carriers occurs, causing the semiconductor material (20) to be thermally heated between the source (S) and the drain (D) and to locally melt, forming at least one permanently conducting channel between the source (S) and the drain (D).
