    摘要: A method for fabricating an integrated circuit includes providing a substrate, forming a low-k dielectric layer over the substrate, etching the low-k dielectric layer to form an opening in the low-k dielectric layer wherein an underlying metal is exposed through the opening, performing a remote plasma treatment to the substrate wherein a plasma used for the remote plasma treatment is generated from a plasma generator separated from a chamber in which the substrate is located, forming a diffusion barrier layer in the opening, and filling the opening with a conductive material. The method preferably includes an in-situ plasma treatment in a same chamber as the step of etching the low-k dielectric layer.

    摘要: A barrier layer and a fabrication thereof are disclosed. The barrier layer comprises at least one barrier material selected from the group consisting of Ta, W, Ti, Ru, Zr, Hf, V, Nb, Cr and Mo and at least one component of oxygen, nitrogen or carbon. A ratio of the component to the barrier material is not less than about 0.45. The fabrication method of the barrier layer applies a working pressure for forming the barrier layer from about 0.5 mTorr to about 200 mTorr substantially without forming crystalline material therein.

    摘要: Provided is a method for forming a composite barrier layer with superior barrier qualities and superior adhesion properties to both dielectric materials and conductive materials as the composite barrier layer extends throughout the semiconductor device. The composite barrier layer may be formed in regions where it is disposed between two conductive layers and in regions where it is disposed between a conductive layer and a dielectric material. The composite barrier layer may consist of various pluralities of layers and the arrangement of layers that form the composite barrier layer may differ as the barrier layer extends throughout different sections of the device. Amorphous layers of the composite barrier layer generally form boundaries with dielectric materials and crystalline layers generally form boundaries with conductive materials such as interconnect materials.
