Latest Patents
One of Carolyn's latest patents focuses on "Copper alloys for interconnections having improved electromigration characteristics and methods of making same." This innovative process involves the formation of copper alloy interconnect lines on integrated circuits by introducing dopant elements into a copper layer. The method includes providing a doping layer over a copper layer, driving dopant material into the copper layer with a high-temperature step, and polishing the copper layer to create individual lines. Additionally, copper alloy interconnect lines can be formed by implanting dopants into individual lines. The process also involves providing a doped seed layer with a capping layer to prevent premature oxidation, forming an overlying copper layer, driving in the dopants, and polishing to form individual lines. This approach enhances electromigration resistance and adhesion characteristics by maintaining higher doping concentrations at the outer portions of an interconnect line while ensuring low electrical resistivity in the interior portions.
