Abstract: Described are methods of forming a semiconductor device. Certain methods comprises depositing a film comprising manganese nitride over a dielectric; depositing a copper seed layer over the film; and depositing a copper fill layer over the copper seed layer. Also described are semiconductor devices. Certain semiconductor devices comprise a low-k dielectric layer; a manganese nitride layer overlying the low-k dielectric layer; a seed layer selected from a copper seed layer or electrochemical deposition seed layer overlying the manganese nitride layer; a copper layer overlying the copper seed layer.
