In one aspect, the electrolessly deposited metal is copper or a copper alloy. In one aspect, the contact level feature is filled with a copper alloy by use of an electroless deposition process. In another aspect, a copper alloy is used to from a thin conductive copper layer that is used to subsequently fill features with a copper containing material by use of an ECP, PVD, CVD, and/or ALD deposition process. In one embodiment, a portion of the barrier layer is purposely allowed to react with traces of residual oxide at the silicon junction of the contact level feature to form a low resistance connection.

摘要： The present invention generally provides an apparatus and method of processing substrates to uniformly remove any residual contamination from the surface of a substrate by use of an appropriate cleaning chemistry and contact with a cleaning medium. In one embodiment, the cleaning medium, such as is a brush or a scrubbing component that is positioned in a cleaning module. In one embodiment, the process of cleaning the surface of a substrate W is completed by “scrubbing” the surface of the substrate while using a cleaning solution that is selected to chemically etch a material from the surface of the substrate. In one aspect, the amount of material removed from the surface of a substrate is only about 10-30 Angstroms (Å). In one embodiment, the substrate surface is cleaned by use of a scrubbing process that uses a fluid that doesn't react with the exposed materials on the surface of the substrate. The fluid is thus used to lubricate the surfaces in contact and to carry any abraded material away from the surface of the substrate. In one aspect, the fluid may be DI water. In one aspect, it may be desirable to add ultrasonic or megasonic agitation to the substrate during the cleaning process to help remove or dislodge material from the surface of the substrate.

摘要翻译： 本发明总体上提供了一种加工基材的装置和方法，以通过使用适当的清洁化学品和与清洁介质的接触来均匀地除去基材表面的任何残余污染物。 在一个实施例中，清洁介质，例如位于清洁模块中的刷子或擦洗部件。 在一个实施例中，清洁衬底W的表面的过程通过“擦洗”衬底的表面而完成，同时使用选择用于从衬底的表面化学蚀刻材料的清洁溶液。 在一个方面，从衬底的表面去除的材料的量仅为约10-30埃（）。 在一个实施例中，通过使用使用不与衬底表面上暴露的材料反应的流体的洗涤过程来清洁衬底表面。 因此，流体用于润滑接触表面并将任何磨损的材料携带离开基底的表面。 在一个方面，流体可以是去离子水。 在一个方面，可能期望在清洁过程中向基底添加超声波或兆声波搅拌以帮助从衬底的表面移除或移除材料。
