Patent ID: 7659168

Claim:
A method of manufacturing an eFuse, comprising: providing a substrate including a layer of insulating oxide and a semiconducting layer above the layer of insulating oxide; forming a diode in the semiconducting layer, wherein forming the diode in the semiconducting layer includes: forming a first heavily-doped region having a first polarity in the semiconducting layer; forming a second heavily-doped region having a second, opposite polarity in the semiconducting layer; and forming a lightly-doped region between the first and second heavily-doped regions in the semiconducting layer; and forming a layer of silicide above the diode, said layer of silicide being patterned to form a fusible conductor lying in contact with said first heavily-doped region, said lightly-doped region, and said second heavily-doped region, said fusible conductor extending from said first heavily-doped region, across said lightly-doped region, and to said second heavily-doped region.
