Patent ID: 8847222

Claim:
A semiconductor device comprising: a first conductive line; a second conductive line, wherein the second conductive line comprises a first end and a second end; a conductive feature disposed between and coupled to the first conductive line and the second conductive line, wherein the conductive feature comprises a first end and a second end, the first end of the second conductive line being coupled to the first end of the conductive feature; a first sense line coupled to the second end of the second conductive line; a second sense line coupled to the first end of the second conductive line; a third sense line coupled to the second end of the conductive feature; a temperature adjuster proximate the conductive feature, wherein when a current is passed through the first conductive line, the conductive feature, and the second conductive line, temperature and/or electromigration in the second conductive line or at the conductive feature is measurable, wherein the temperature and/or electromigration in the second conductive line is measurable using the first sense line and the second sense line, wherein the temperature and/or electromigration at the conductive feature is measurable using the second sense line and the third sense line; and a feedback device coupled to the temperature adjuster and the conductive feature.
