Methods and apparatuses for reflowing conductive elements of semiconductor devices

Abstract:

Methods of reflowing electrically conductive elements on a wafer may involve directing a laser beam toward a region of a surface of a wafer supported on a film of a film frame to reflow at least one electrically conductive element on the surface of the wafer. In some embodiments, the wafer may be detached from a carrier substrate and be secured to the film frame before laser reflow. Apparatus for performing the methods, and methods of repairing previously reflowed conductive elements on a wafer are also disclosed.
