ABSTRACT:
A programmable antifuse element comprising adjacent bodies of germanium and aluminum or aluminum allow form a low resistance connection of good mechanical and thermal properties when heated to a temperature where alloying of the aluminum and germanium occurs. Heating for the purpose of programming the antifuse element can be done by electrical resistance heating in the-germanium, which may be doped to achieve a desired resistance value, or by laser irradiation. Due to the high resistance of intrinsic or lightly doped germanium, a resistance change ratio of greater than 10,000:1 is achieved.
