LASER-BASED METHOD AND SYSTEM FOR PROCESSING A MULTI-MATERIAL DEVICE HAVING CONDUCTIVE LINKS STRUCTURES

摘要

A laser-based method and system for selectively processing a multi-material device having a target link structure formed on a substrate while avoiding undesirable change to an adjacent link structure also formed on the substrate are disclosed. The method includes applying at least one focused laser pulse having a wavelength into a spot. The at least one focused laser pulse has an energy density over the spot sufficient to completely process the target link structure while avoiding undesirable change to the adjacent link structure, the substrate and any layers between the substrate and the link structures. The target link structure and the adjacent structure may have a pitch of about 2.0 microns or less.
