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.

摘要： A method of forming an integrated circuit structure includes providing a semiconductor substrate; forming patterned features over the semiconductor substrate, wherein gaps are formed between the patterned features; filling the gaps with a first filling material, wherein the first filling material has a first top surface higher than top surfaces of the patterned features; and performing a first planarization to lower the top surface of the first filling material, until the top surfaces of the patterned features are exposed. The method further includes depositing a second filling material, wherein the second filling material has a second top surface higher than the top surfaces of the patterned features; and performing a second planarization to lower the top surface of the second filling material, until the top surfaces of the patterned features are exposed.
