    摘要: Methods and devices for patterning electroless metals on a substrate are presented. An active catalyst layer on the substrate can be covered with a patterned mask and treated with a deactivating chemical reagent, which deactivates the catalyst layer not covered by the mask. Once the patterned mask is removed, the electroless metal layer can be placed to have a patterned electroless metals. Alternatively, a substrate can be coated with a blocking reagent in a pattern first to inhibit formation of the catalyst layer before a catalyst layer can be placed over the blocking agent layer and then electroless metal layer is placed on the catalyst layer. The pattern of the blocking reagent acts as a negative pattern of the final conductive line pattern.

    摘要: A pre-treatment method of plating and a plating system can perform a uniform plating process in which sufficient adhesivity on a surface of a substrate is obtained. The pre-treatment method of plating includes a coupling layer forming process of forming a titanium-based coupling layer 21b on the surface of the substrate with a titanium coupling agent; and a coupling layer modification process of modifying a surface of the titanium-based coupling layer 21b with a modifying liquid after the coupling layer forming process.

    摘要: Disclosed herein are various methods of filing voids in copper conductive structures on integrated circuit devices. In one example, the method includes the steps of forming a conductive copper structure in a layer of insulating material and performing an electroless deposition process to selectively form a fill layer comprised of a conductive material on the copper containing structure, the fill layer being adapted to at least partially fill any voids that may exist in the conductive copper structure.
