Abstract(in English) | In the present work, CuAl alloy seed was applied for 90nm node Cu dual-damascene interconnects and its effect on reliability improvement was studied. Via reliability of Cu interconnects using CuAl alloy seed was greatly improved without a remarkable increase in via resistance. A small amount of Al in Cu seems to help prevent the diffusion of vacancies and Cu atoms in Cu interconnects. Using CuAl alloy seed is one of the most promising and simple techniques to improve the via reliability of Cu interconnects for the 65nm node and beyond. |
