Patent application numberDescriptionPublished
20080226826Substrate Processing Method and Substrate Processing Apparatus - A substrate processing method includes applying electroless plating of CoWB onto a Cu interconnection line formed on a wafer W, and then performing a post-cleaning process by use of a cleaning liquid on the target substrate or wafer before a by-product is precipitated on the surface of the CoWB film formed by the electroless plating to cover the Cu interconnection line.09-18-2008
20080280437Substrate Processing Method and Substrate Processing Apparatus - A CoWB film is formed as a cap metal on a Cu interconnection line formed on a substrate or wafer W, by repeating a plating step and a post-cleaning step a plurality of times. The plating step is arranged to apply electroless plating containing CoWB onto the Cu interconnection line. The post-cleaning step is arranged to clean the wafer W by use of a cleaning liquid, after the plating step.11-13-2008
