Abstract:
A programmable structure, comprising:a first lower metallization line defined on a first metallization layer; a second lower metallization line defined on the first metallization layer, the first and second lower metallization lines being electrically connected; a first upper metallization line defined on a second metallization layer; a second upper metallization line defined on the second metallization layer; a conductively filled via electrically connecting the second lower metallization line to the second upper metallization line; an eroded via defined between the first lower metallization line and the first upper metallization line; and an electrical connection being defined between a first point on the second upper metallization line and a second point on the first lower metallization line, the electrical connection being capable of forming an electron flow originating at the second point of the first lower metallization line and leading to the first point of the second upper metallization line, such that electron flow causes metallization of the first lower metallization line to flow into the eroded via and form a hard-wired link.
