    摘要: A method and cleaning solution that removes contaminants from a dielectric material and polished surfaces of copper interconnect structures prior to an electroless deposition of a capping layer without substantially adversely affecting the interconnect formed therefrom are disclosed. The cleaning solution includes combinations of a core mixture and sulfuric acid or sulfonic compounds such as sulfonic acids that include methanesulfonic acid. In one embodiment, the core mixture includes a citric acid solution and a pH adjuster such as tetra-methyl ammonium hydroxide or ammonia. One embodiment of the method includes providing a planarized substrate, applying the cleaning solution to the substrate to simultaneously clean at least one metal feature and a dielectric material of the substrate, and depositing the metal capping layer selectively on the at least one metal feature using electroless deposition.

    摘要: An apparatus and a method of controlling an electroless deposition process by directing electromagnetic radiation towards the surface of a substrate and detecting the change in intensity of the electromagnetic radiation at one or more wavelengths reflected off features on the surface of the substrate. In one embodiment the detected end of an electroless deposition process step is measured while the substrate is moved relative to the detection mechanism. In another embodiment multiple detection points are used to monitor the state of the deposition process across the surface of the substrate. In one embodiment the detection mechanism is immersed in the electroless deposition fluid on the substrate. In one embodiment a controller is used to monitor, store, and/or control the electroless deposition process by use of stored process values, comparison of data collected at different times, and various calculated time dependent data.
