Abstract:
Back end of the line precision resistors that allow for high currents and for configuration as an eFuse by embedding a single thin film high resistive metal material within a dielectric layer, wherein the resisters are coupled to sidewalls of adjacent metal interconnects are described. The resistors can be formed in the metal one (M1) dielectric layer and can be coupled to sidewalls of the M1 interconnects. Also described are processes for fabricating integrated circuits including the resistors and/or e-Fuses.

Claim (Index 10):
A process for fabricating a back end of line resistor, the process comprising:\n depositing a dielectric layer onto a substrate; patterning the dielectric layer to form a plurality of trenches; removing a portion of the dielectric layer between at least two adjacent trenches to form a recess; conformally depositing a metal layer onto the dielectric layer; depositing a metal conductor onto the metal layer filling the trenches and forming an overburden thereon; removing the overburden to form metal interconnects, wherein the metal layer remains on a surface of the recessed dielectric layer so as to define a resistor, and wherein the resistor has sidewalls, wherein only the resistor sidewalls are electrically coupled to sidewalls of the at least two adjacent metal interconnects; and depositing a cap layer onto the resistor and the dielectric layer, wherein the resistor is embedded within the dielectric layer.
