Abstract: An integrated circuit structure and method of making the same is disclosed, in which the adhesion of copper conductors (12, 22) to a low-dielectric constant insulating layer (10, 16) is improved. During the fabrication of the structure, exposed surfaces of the low-k insulating layers (10, 16), including the surfaces of these layers within contact, via, or trench openings, are exposed to nitrogen gas, preferably in a sputtering chamber. An optional plasma treatment of the insulating layers (10, 16) in the presence of nitrogen gas may also be performed. As a result, the surface portions of the insulating layers (10, 16) is made to be nitrogen-rich. A liner layer (8, 21) is then formed by reactive sputtering of tantalum nitride over the nitrogen-rich surfaces of the insulating layers (10, 16), followed by the sputtering of tantalum. Copper electrodes (12, 22) are then deposited into the openings in the corresponding insulating layers (10, 16) with improved adhesion resulting.

Abstract: An apparatus and method for depositing thin films on the surface of a device such as a spherical shaped devices. The apparatus includes an enclosure containing a plurality of apertures and a conductor coil. The apertures connect to conduits for inputting and outputting the devices as well as injecting and releasing different gases and/or processing constituents. A chamber is formed within the enclosure and is configured to be coaxial with the conductor coil. Devices move through the input conduit where they are preheated by a resistance-type furnace. The preheated devices then move into the chamber where chemical precursors are added and the devices are further heated to a predefined temperature associated with the chemical precursors by radio frequency energy from the conductor coil. At this time, the gases and/or processing constituents react with the heated device thereby growing a thin film on its outer surface.
