The diamond-like coating has a contact surface having a coefficient of friction of less than about 0.3, a hardness of at least about 8 GPa, and a metal concentration level of less than about 5×1012 atoms/cm2 of metal.

Abstract: A method for processing a substrate comprising the formation of a metal nitride/metal stack suitable for use as a barrier/liner for sub-0.18 &mgr;m device fabrication. After a metal nitride layer is deposited upon a metal layer, the metal nitride layer is exposed to a treatment step in a nitrogen-containing environment, e.g., a plasma. The plasma treatment modifies the entire metal nitride layer and a top portion of the underlying metal layer. The plasma adds nitrogen to the top portion of the metal layer, resulting in the formation of a nitrated-metal layer. Aside from reducing the microstructure mismatch across the nitride-metal interface, the plasma treatment also densifies and reduces impurities from the deposited nitride layer. The resulting nitride/metal stack exhibits improved film properties, including enhanced adhesion and barrier characteristics. A composite nitride layer of a desired thickness can also be formed by repeating the deposition and treatment cycles of thinner component nitride layers.

Abstract: A valve arrangement is provided that more effectively purges processing liquid from a processing liquid delivery system. With the valve arrangement only a small portion of the processing liquid path having a small wetting perimeter must be purged to affect replacement of a dysfunctional injection valve or any other component within the processing liquid delivery system. The valve arrangement comprises a first and a second isolation valve, a pump valve and purge valve configured to reduce the wetting perimeter defined by the four valves. The valve arrangement allows a dysfunctional injection valve or any other component to be replaced without health risk to humans or damage risk to a processing liquid delivery system employing the valve arrangement. During component replacement, the first and the second isolation valves are closed and the pump and the purge valves are opened so as to purge processing liquid from the isolated volume defined by the four valves.

Abstract: The present invention provides an apparatus and method for measuring the temperature of a moving radiant object. A probe, such as a pyrometer, is disposed in an opening of a vacuum chamber adjacent a radiation transparent window. The probe defines an optical path which intercepts the radiant object entering or exiting a processing chamber. The radiant object is moved through the optical path and emits electromagnetic waves. The electromagnetic waves are collected by the probe and transmitted to a signal processing unit where the waves are detected and converted to a temperature reading. If desired, the accumulated data may then be used to generate a cooling curve representing the thermal effects experienced by the radiant object. Extrapolation or correlation methods may be used to extend the cooling curve to points in time prior to or after the data collected by the probe.

Abstract: A continuous process for the deposition of robust titanium-containing barrier layers comprises sputtering in a single substrate sputtering chamber a first layer of titanium, sputtering a layer of titanium nitride thereover, treating the titanium nitride layer with a plasma containing oxygen while continuing to sputter the titanium target to deposit a thin layer of TiON, and finally sputtering a layer of titanium over the titanium nitride. The latter step removes impurities from the titanium target, preventing poisoning of the target. Thus subsequent substrates can be continuously processed in said chamber without degrading the barrier properties or poisoning the titanium target.
