Abstract:
A method of printing transferable components includes pressing a stamp (10) including at least one transferable semiconductor component (20) thereon on a target substrate (30) such that the at least one transferable component and a surface of the target substrate contact opposite surfaces of a conductive eutectic layer (31). During pressing of the stamp on the target substrate, the at least one transferable component is exposed to electromagnetic radiation (4) that is directed through the transfer stamp to reflow the eutectic layer. The stamp is then separated from the target substrate to delaminate the at least one transferable component from the stamp and print the at least one transferable component onto the surface of the target substrate. Related systems and methods are also discussed.
