Abstract
A process for electrolessly depositing cobalt-tin alloys with adjustable tin contents from 1 to over 25 atomic percent tin is disclosed. The deposited alloy is useful in the electronics and computer industries for device, chip interconnection and packaging applications. When used for chip interconnection applications, for example, the invention replaces the currently used complicated ball-limiting-metallurgy. The invention may also be used to inhibit hillock formation and electromigration in copper wire structures found in computers and micron dimension electronic devices.
