    Abstract: Methods and apparatus for forming an embedded antifuse in a wafer-level packaging compatible process. In some embodiments, a method for forming an embedded antifuse includes forming a first redistribution layer on a first polymer layer, depositing an antifuse dielectric layer on the first redistribution layer, forming a second polymer layer on the antifuse dielectric layer, creating at least one first via through the second polymer layer to the antifuse dielectric layer using a lithography process with, for example, a dielectric etch, and forming a second redistribution layer on the second polymer layer and contacting the antifuse dielectric layer at a bottom of the at least one first via.
