ALLOY ELECTRODEPOSITION FOR ELECTRONIC APPLICATIONS

Alloy thin films of interest for possible electronic applications were obtained by electrodeposition: Ni-Fe for magnetic heads, Co alloys fo r magnetic recording and Cu-Sb as a possible underlayer for electric c ontacts. Permalloy ECD Ni-Fe films were deposited from acid baths on S i wafers, patterned by photolithography; Co-Pt and Co-Pd films from ba ths of similar composition, obtaining hard Co-Pt and soft Co-Pd layers ; Cu-Sb as oversaturated solid solutions or as multilayers depending o n the deposition conditions. Electrokinetic behaviour and related stru ctures are interpreted by means of the normality-inertia parameter P(n i).
